Top 10 Cloud Server Hosting Providers Reviews

Cloud Computing Service Providers: Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. Also one should learn about various cloud computing providers to avail the facility of cloud computing, here we are going to discuss providers in detail. But before that let’s understand what is meant by cloud.

In cloud computing, the word cloud (also phrased as “the cloud”) is used as a metaphor for “the Internet,” so the phrase cloud computing means “a type of Internet-based computing,” where different services — such as servers, storage and applications — are delivered to an organization’s computers and devices through the Internet. In other words, cloud computing is taking services (“cloud services”) and moving them outside an organizations firewall on shared systems.

Cloud Server Hosting is based on the most innovative Cloud computing technologies that allow unlimited number of machines to act as one system. Other hosting solutions (shared or dedicated) depend on one machine only, while cloud server hosting security is guaranteed by many servers. The cloud technology allows easy integration of extra resources, such as space or RAM and thus enable website growth.

Basically, Cloud Server Hosting is an IaaS cloud delivery model that offers virtual services like data hosting or solutions to websites. It is delivered on an on-demand basis, where the client can tap into the services as much as they need to, and pay for only what they use.
 
This type of hosting is enabled through virtualization, where the computing capability of a data center is distributed simultaneously among multiple users. The user can utilize the underlying infrastructure to host their applications, data, or services. Cloud Server hosting services offer hosting to websites on virtual servers which utilize computing resources from wide, extensive networks of physical web servers. These networks of servers are vast and may be placed in different data centers located at different places.
 
Cloud Server hosting can be considered an alternative to hosting websites on single servers, whether dedicated or shared. It can even be thought of as an extension of the basic idea of clustered hosting in which multiple servers host websites.

Different Types of Cloud Service Providers

 
Cloud Server Hosting can combine the capacity of several servers to offer a single cloud hosted server. This type of hosting offers enormous flexibility in scaling hosting resources. Cloud storage, cloud desktops, cloud servers – these are some examples of cloud server hosted solutions.

Cloud Hosting Benefits:

  • Flexibility and scalability: extra resource can be accessed as and when required
  • Cost-effectiveness: whilst being available when needed, clients only pay for what they are using at a particular time
  • Ease of set up: Cloud servers do not require much initial setup
  • Reliability: due to the number of available servers, if there are problems with some, the resource will be shifted so that clients are unaffected.
  • Lower pricing and generous features
  • Highest level of website performance guaranteed by multiple machines
  • Guaranteed server resources (CPU, RAM)

So let’s start to learn cloud computing and that too with an example.

You might had travelled many times by bus or train, so whenever you travel through any of these means of travelling vehicles you just take a ticket for your destination and hold up back to your seat till the time you don’t get reached to your destination.  Likewise other passengers do the same take tickets and wait for their destination. And it hardly bothers you that where other passengers are going and as you reach to your destination you get off the bus. Same is with the cloud computing, it is just like the bus, that carries data and information for the various users you as well and allows all to use its services in minimum cost. So in this cloud computing tutorial you are going to learn about

Why named as “Cloud”?

Most of you will be wondering that from where the word cloud came from so here is the answer to your question. The term “Cloud” came from the network design that was basically used by the network engineers to represent the location of the various network devices and also their inter-connection. The shape of the network was almost like a cloud so named as the cloud computing.

Why Cloud Computing?

As day by day users of mobile and computer are increasing, due to which data storage has become one of the priorities for this field. Much large as well as small-scale businesses today thrive on data and also spend a lot of money to maintain and secure this data. Cloud computing requires a storage hub and strong IT support. As most of the small scale businesses are not able to afford the costing of the in-house IT  infrastructure and the back up support services. For all them cloud computing can be proved to be a cheaper solution.   Also due to its best services like data storing efficiency, computation and less cost of maintenance have succeeded to attract even bigger businesses also.

Cloud computing directly minimises the software and hardware requirements form the user’s side. The only thing which the user will be able to run is cloud computing system, interface software, that can be as simple as the Web Browser and rest of the other things are taken care by the cloud. If cloud computing is new to you, then I also you have used it if you have used gmail, Hotmail, and yahoo all of them are just like what cloud computing offers to its users. As while accessing the email service the data is stored on the cloud server and not on our computer or hard drive. The technology as well as the infrastructure on which the cloud is based are not visible to us but still we are able to make use of its services. It is also not important that whether the cloud service is based on the Ruby, PHP, HTTP, XML or anyother specific technologies till the time it is user friendly and functional as well. Also an individual user can connect to the cloud system from their own device such as mobile, desktop or even a laptop.

Cloud computing is such a boon for the small businesses as it allows them to make of those technologies and services that were out of their reach.

Benefits of Cloud Computing

One of the major advantage of using the cloud computing services is that it very much cost efficient that’s why it is adopted most of the organizatios small or big. Cloud computing also offers the freedom to use the services as per the requirement of the individual or organization and also pay for the same what you use. Many other benefits of using cloud computing are as follows:

  • Improved performance
  • Lower costs of the IT infrastructure and computer costs.
  • Less maintenance problems
  • Various instant software updates
  • Better and improved compatibility between the operating systems
  • Back up as well as recovery
  • Increased data safety
  • More storage capacity
  • Backup and Recovery

Various types of Cloud

There are mainly 4 different types of the cloud models that you can choose form according to your business needs:

  1. Private Cloud: Here , all the computing services are being deployed for only one particular organization. This model is basically used for the intra business interactions, where all the computing resources are owned, governed as well as operated by the single organization.
  2. Community Cloud: Here the computing resources/ services are provided for a whole community or organization.
  3. Public Cloud: This type of the computing resource is ideally used for the B2C type of interactions that means  Business to Customer type. Here all the resources are owned as well as governed by government, academic or any business organization.
  4. Hybrid Cloud: This type of cloud makes use of both public as well as private cloud. So organizations using this type of cloud can take benefit of both public as well as private resources.

All these were the models that were offered by the cloud computing now we are going to tell you about the services of cloud computing.

  1. Software as a Service (SaaS)
  2. Platform as a Service (PaaS)
  3. Infrastructure as a Service (IaaS)

The services offered by the cloud computing are used as per the requirement of businesses.

SaaS (Software as a Service)

SaaS is a software distribution model where applications are hosted by the service provider or the vendor and are available to the customers via

SaaS is a software distribution model where applications are hosted by the service provider or the vendor and are available to the customers via internet. It has become one of the most preferred technologies which supports Service Oriented Architecture (SOA) or the web services.

This service is available to the users anywhere in the world. First of all, these software applications are required to be purchased and install it into on your own computer. The users of SaaS don’t follow this step, instead of this they subscribe to it on the monthly basis. There are so many tasks which can be easily performed using SaaS such as invoicing, sales, accounting and planning.

PaaS (Platform as a Service)

PaaS provides the environment and the platform and allows the developers to build the applications as well as services also. The service is then hosted in cloud and then can be accesses by all its users through internet. The services which are offered by the PaaS is constantly updated and many new features are also added on regular basis. Mostly web developers, software developers and businesses can take advantage of the PaaS. It provides the application to all its users a platform to support the application development. PaaS includes so many services such as networking, management services, testing, storage, deploying, collaborating, managing applications and hosting as well.

IaaS (Infrastructure as a Service)

It is one of the fundamental service along side the PaaS. IaaS provides the facilities to access the computing resources in the virtualized environment “cloud” on the internet. IaaS provides the computing infrastructure such as network connections, virtual server space, load balancers, bandwidth and ID addresses.

Cloud Computing Video Tutorial

Below is cloud computing video tutorial from which you can learn about all the aspects of cloud computing.This is one of the best cloud tutorial that you will find on the web.

Cloud Computing Architecture

Now let’s see what all components cloud computing is comprised of to understand it in much deep.

Cloud computing mostly consists of the two main parts or ends i.e. front end and back end. Front end is comprised of the  client part of the cloud computing system.  It consists of  the applications and interfaces which are required to access cloud computing platform.

Whereas the backend part is referred to cloud, and consists of the resources which are required for the cloud computing services. Basically it consists of the virtual machines, data storage, servers and security mechanism etc. Backend is under the control of the providers. Cloud computing divides file system which spreads over the multiple hard disks as well as machines. Here the data/ information is never stored at a one place as if in case one unit fails then other one will take over automatically so that the data don’t get lost.

The user disk space has been allocated on to the distributed file system, where as another important part is the algorithm for the resource allocation. Cloud is one of the strong distributed environment that depends on the strong algorithm.

Virtualization and Cloud Computing

As most of the people are not aware of the fact that the main anabling technology for the cloud computing is virtualization. Virtualization can be defined as the division of the single physical server into the multiple logical servers. As once the physical server gets divided in to the many multiple logical servers then each of the logical server behaves as the  physical server and can run the operating system as well as applications itself.

Many popular and known companies provide the facility of virtualization service, and instead of using your personal PC for the storage and computation purpose  you just need to use their virtual server. As they are much cost effective, fast and consumes very less time. Vitualization is mainly  used for the 3 main purpose such as:

  1. Network Virtualization
  2. Server Virtualization
  3. Storage Virtualization

So lets discuss all these three  in detail.

Natural Virtualization: In natural virtualization, available resources are combined by splitting up the available bandwidth into the different channels, and each of it is independent from each other and that can be assigned to some specific server or the device in real time.

Server Virtualization: It is the process of masking of the resources of the server such as RAM, operating system,  processors etc from the server users. The main working of server virtualization is to maximise the resource sharing and also the decrese the burden as well as complexity of the computation from the users.

Storage Virtualization: It is grouping of the physical storage from the various multiple network storage devices into the single storage device which is managed from the central console.  It is basically used in the storage area networks (SANs).

To unlock the Cloud computing system, virtualization is considered to be as the main key, also the virtualization is important for the cloud as it decouples software from the hardware. For example if we see, Personal computers can use the virtual memory to borrow the extra memory from hard disk. Hard disk carries much more space as compared to the memory. Although this is also a fact that virtual disks are  much slower than the real memory but if this can be managed properly then it can work much better. Also there is a software that can imitate like an entire PC, which means a single PC can perform all the tasks that 20 PCs will perform.

Cloud Computing Vs Grid Computing

Have you ever thought that from where you get the electricity and how it is generated, and when you switch any of your electric device what is all behind it. The electricity or what we say power supply that we get at our homes travels through  a chain of network which basically includes the power stations, power lines, transformers and transmission stations. All these components ltogether make a “Power Grid”. Like that only in cloud computing there is “Grid Computing” is an infrastructure which links all the computing resources like  we can say servers, workstations, PCs and storage elements and also provides mechanism that re required to access the resources.

Grid computing can be considered as the middle point to communicate  or to coordinate the disparate IT resources across a network which allows them, to functional as a whole. It is much more utilised in the scientific research and also in the universities for the educational purpose.

There is major confucion between the cloud computing and grid computing to most of the people, as there functions are almost similar but the approach they take are very different.  So lets have alook that how they are operated.

Cloud Computing                            Grid Computing
·         Cloud computing works more as a service provider for utilizing computer resource ·         Grid computing uses the available resource and interconnected computer systems to accomplish a common goal
·         Cloud computing is a centralized model ·         Grid computing is a decentralized model, where the computation could occur over many administrative model
·         Cloud is a collection of computers usually owned by a single party.

·

·         A grid is a collection of computers which is owned by a multiple parties in multiple locations and connected together so that users can share the combined power of resources
·         Cloud offers more services all most all the services like web hosting, DB (Data Base) support and much more ·         Grid provides limited services
·         Cloud computing is typically provided within a single organization (eg : Amazon) ·         Grid computing federates the resources located within different organization.


Difference between Cloud Computing and Utility Computing

Woman online shopping with a credit card – isolated over white background

Above we learnt about the differences between the cloud computing and grid computing. So here let’s compare it with the utility computing. Utility computing is like that the electricity that we use as per requirement and then pay the bill for that, like that only cloud computing also uses the model pay as per the use. Utility computing is best for the Small busineesmall scale usage and it can be utilised in any server environment and it requires the cloud computing.

Utility is the method of providing all the service through as per the demand comes and pay per use billing method. The cient has the access of virtually unlimited supply of the computing solutions over the VPN or over internet that can be sources and used whenever required.

Small businesses can make use of the utility computing and that too in the limited budget and can use the software such as Customer Relationship Management without much investing on the infrastructure part to maintain the client base.

Here are some of the main differences between the utility computing and cloud computing.

Utility Computing                          Cloud Computing
·         Utility computing refers to the ability to charge the offered services, and charge customers for exact usage ·         Cloud Computing also works like utility computing, you pay only for what you use but Cloud Computing might be cheaper, as such, Cloud based app can be up and running in days or weeks.
·         Utility computing users want to be in control of the geographical location of the infrastructure ·         In cloud computing, provider is in complete control of cloud computing services and infrastructure
·         Utility computing is more favorable when performance and selection infrastructure is critical ·         Cloud computing is great and easy to use when the selection infrastructure and performance is not critical
·         Utility computing is a good choice for less resource demanding ·         Cloud computing is a good choice for high resource demanding
·         Utility computing refers to a business model ·         Cloud computing refers to the underlying IT architecture


Security issues for Cloud Computing

While using the cloud computing one of the major issues that one feels is the security One of the concern while utilising the cloud computing is  that the cloud providers have the access to the customers  unencrypted data either it is saved on the disk, memory or is transmitted over network.

With all these concerns taking care of cloud computing provider companies have joined hand with the Trusted Computing Group (TCG), all of these are non- profit organizations that actually releases the set of the specifications to secure the hardware, create some self encrypting drives and to improve the network security. This actually protects data from the data kits and malware. Now cloud computing have been moved or expanded to many different types of the devices such as mobile phones and hard disk drives, so for that TCG have extended their security measures to include all these devices within itself. TCG provides the capability to create the unified data protection policy across all the clouds.

Some of the most trusted brands that offer cloud services are Gmail, Amazon, Box.net and many other.

Privacy concern & Cloud Computing

Privacy is one of the most important aspect  in which most of the services get fail, also it is one of the strong barrier for all the users to adapt in the cloud computing systems. In the cloud computing this is the same issue of privacy. So, this is a major concern in which mot of the service providers still need to think.

Advantages of Cloud Computing:

  • Fresh Software

With SaaS, the latest versions of the applications needed to run the business are made available to all customers as soon as they’re released. Immediate upgrades put new features and functionality into workers’ hands to make them more productive. What’s more, software enhancements are typically released quite frequently. This is in contrast to home grown or purchased software that might have major new releases only once a year or so and take significant time to roll out.

  • Do more with less

With cloud computing, companies can reduce the size of their own data centres — or eliminate their data centre footprint altogether. The reduction of the numbers of servers, the software cost, and the number of staff can significantly reduce IT costs without impacting an organization’s IT capabilities.

  • Flexible costs

The costs of cloud computing are much more flexible than traditional methods. Companies only need to commission – and thus only pay for – server and infrastructure capacity as and when it is needed. More capacity can be provisioned for peak times and then de-provisioned when no longer needed. Traditional computing requires buying capacity sufficient for peak times and allowing it to sit idle the rest of the time.

  • Always-on availability

Most cloud providers are extremely reliable in providing their services, with many maintaining 99.99% uptime. The connection is always on and as long as workers have an Internet connection, they can get to the applications they need from practically anywhere. Some applications even work off-line.

  • Improved mobility

Data and applications are available to employees no matter where they are in the world. Workers can take their work anywhere via smart phones and tablets—roaming through a retail store to check customers out, visiting customers in their homes or offices, working in the field or at a plant, etc.

  • Improved collaboration

Cloud applications improve collaboration by allowing dispersed groups of people to meet virtually and easily share information in real time and via shared storage. This capability can reduce time-to-market and improve product development and customer service.

  • Cloud computing is more cost effective

Because companies don’t have to purchase equipment and build out and operate a data center, they don’t have to spend significant money on hardware, facilities, utilities and other aspects of operations. With traditional computing, a company can spend millions before it gets any value from its investment in the data center.

  •  Expenses can be quickly reduced

During times of recession or business cut-backs (like the energy industry is currently experiencing), cloud computing offers a flexible cost structure, thereby limiting exposure.

  •  Flexible capacity

Cloud is the flexible facility that can be turned up, down or off depending upon circumstances. For example, a sales promotion might be wildly popular, and capacity can be added quickly to avoid crashing servers and losing sales. When the sale is over, capacity can shrink to reduce costs.

  • Facilitate M&A activity

Cloud computing accommodates faster changes so that two companies can become one much faster and more efficiently. Traditional computing might require years of migrating applications and decommissioning data centers before two companies are running on the same IT stack.

  • Less environmental impact

With fewer data centers worldwide and more efficient operations, we are collectively having less of an impact on the environment. Companies who use shared resources improve their ‘green’ credentials.

Disadvantages of Cloud Computing:

Common risks are:

  • data loss or theft
  • data leakage
  • account or service hijacking
  • insecure interfaces and APIs
  • denial of service attacks
  • technology vulnerabilities, especially on shared environments
  • Net Connection:

For cloud computing, an internet connection is a must to access your precious data.

  • Low Bandwidth:

With a low bandwidth net, the benefits of Cloud computing cannot be utilized. Sometimes even a high bandwidth satellite connection can lead to poor quality performance due to high latency.

  • Affected Quality:

The internet is used for various reasons such as listening to audios, watching videos online, downloading and uploading heavy files, printing from the cloud and the list goes on. The quality of Cloud computing connection can get affected when a lot of people utilize the net at the same time.

  • Security Issues:

Of course, cloud computing keeps your data secure. But for maintaining complete security, an IT consulting firm’s assistance and advice is important. Else, the business can become vulnerable to hackers and threats.

  • Non-negotiable Agreements:

Some cloud computing vendors have non-negotiable contracts for the companies. It can be disadvantageous for a lot of businesses.

  • Cost Comparison:

Cloud software may look like an affordable option when compared to an in-house installation of software. But it is important to compare the features of the installed software and the cloud software. As some specific features in the cloud software can be missing that might be essential for your business. Sometimes you are charged extra for unrequired additional features.

  • No Hard Drive:

As Steve Jobs, the late chairman of Apple had exclaimed “I don’t need a hard disk on my computer if I can get to the server faster… carrying around these non-connected computers is byzantine by comparison.” But some people who use programs cannot do without an attached hard drive.

  • Lack of full support:

Cloud-based services do not always provide proper support to the customers. The vendors are not available on e-mail or phones and want the consumers to depend on FAQ and online community for support. Due to this, complete transparency is never offered.

  • Incompatibility:

Sometimes, there are problems of software incompatibility. As some applications, tools, and software connect particularly to a personal computer.

  • Lack of insight into your network:

It’s true cloud computing companies provide you access to data like CPU, RAM, and disk utilization. But just think once how minimal your insight becomes into your network. So, if it’s a bug in your code, a hardware problem or anything, without recognizing the issue it is impossible to fix it.

  • Minimal flexibility:

The application and services run on a remote server. Due to this, enterprises using cloud computing have minimal control over the functions of the software as well as hardware. The applications can never be run locally due to the remote software.

To conclude, Cloud computing is a quickly changing area that will undoubtedly continue to play an increasingly major role for non-profits, charities, and libraries as well as their IT systems. But which elements of your IT infrastructure you should move into the cloud — and when — will vary a lot from organization to organization.

There are pros and cons of cloud but cloud has become a mandatory part of every business venture. Today, one cannot think without enjoying the benefits of cloud computing. With careful precautions and efforts, the disadvantages of cloud computing can be minimized. It’s true that cloud computing has rocked the business world. The pros outweigh the cons of cloud computing. The minimized costs, easy access, data backup, data centralization, sharing capabilities, security, free storage and quick testing speaks for itself. The argument becomes even stronger with the enhanced flexibility and dependability.

So this was all about the cloud computing tutorial, the tutorial is provided in the video as well as pdf format. For any query you can leave a comment below, we will reply you at the earliest.

 

What is Cloud Computing in Simple Terms

Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics and more over the internet referred as a cloud.  Here we are going to tell you about what is cloud computing, its services, applications, advantages, and much more, so let’s start with its definition.

The term “cloud” appears to have its origins in network diagrams which represented the internet and other parts of it as a schematic cloud. This concept is representative of what happens when applications and services are moved into the internet “cloud”. It is not something that appeared overnight, some form of it can be traced back to a time when computer systems remotely time-shared computing resources and applications. One thing to be assured of while using the devices of these services and applications is that they do not require any special applications.

One thing to be assured of while using the devices of these services and applications is that they do not require any special applications. The companies which provide these services are called as cloud providers and typically charge for computing services based on usage which is calculated in the similar way of calculating water or electricity bill at home. The first cloud technology service is barely a decade old, but already a variety of organizations ranging from tiny startups to global corporations, government agencies to non-profits, are embracing this technology for all sorts of reasons.

Origin of Cloud Computing term

The origin of the term cloud computing is unclear. The word “cloud” is commonly used in science to describe a large agglomeration of objects that visually appear from a distance as a cloud and describes any set of things whose details are not further inspected in a given context. Another explanation is that the old programs that drew network schematics surrounded the icons for servers with a circle, and a cluster of servers in a network diagram had several overlapping circles, which resembled a cloud. In analogy to the above usage, the word cloud was used as a metaphor for the Internet and a standardized cloud-like shape was used to denote a network on telephony schematics. Later it was used to depict the Internet in computer network diagrams. With this simplification, the implication is that the specifics of how the end points of a network are connected are not relevant for the purposes of understanding the diagram. The cloud symbol was used to represent networks of computing equipment in the original ARPANET by as early as 1977,[and the CSNET by 1981—both predecessors to the Internet itself.

The term cloud has been used to refer to platforms for distributed computing. In Wired’s April 1994 feature “Bill and Andy’s Excellent Adventure II” on the Apple spin-off General Magic, Andy Hertzfeld commented on General Magic’s distributed programming language Telescript that:

“The beauty of Telescript … is that now, instead of just having a device to program, we now have the entire Cloud out there, where a single program can go and travel to many different sources of information and create sort of a virtual service. No one had conceived that before. The example Jim White [the designer of Telescript, X.400 and ASN.1] uses now is a date-arranging service where a software agent goes to the flower store and orders flowers and then goes to the ticket shop and gets the tickets for the show, and everything is communicated to both parties.

References to “cloud computing” in its modern sense appeared as early as 1996, with the earliest known mention in a Compaq internal document. The popularization of the term can be traced to 2006 when Amazon.com introduced its Elastic Compute Cloud.

 

Cloud Computing Definition & basics

Cloud computing basics include activities like creating new apps and services, storing, backing up and recovery of data, hosting websites and blogs, audio, and video streaming, etc. With the advent of this technology, there has been a big shift from the traditional way businesses thought about IT resources. There are some queries regarding this technology like what is cloud ? And why is it so popular? The reason for this is that it eliminates the capital expense of buying hardware and software and setting up and running on-site data centers. This leads to savings of a large amount of money. Since most of the services are provided self-service and on-demand in order to provision vast amounts of computing resources in minutes with just a few mouse clicks to give businesses a lot of flexibility. These services have the ability to scale elastically at the global level. In cloud speak, which means delivering the right amount of IT resources with more or less computing power, storage, right bandwidth, whenever needed and from the right geographic location. The on-site data centers require a lot of racking and stacking of hardware set up, software patching and other time-consuming IT management chores. Cloud computing removes the need for these many tasks so that the IT teams can now spend time on achieving more important business goals. One of the crucial advantages of cloud computing is that of performance and reliability.

History

The concept of Cloud computing came into existence in 1950, along with the implementation of mainframe computers being accessible via thin or static clients. Cloud computing has evolved from static clients to dynamic ones and from software to services. The following diagram represents the evolution of cloud computing.

Benefits of basic cloud computing

concept of Cloud computing

  • Access to applications as utilities over the internet
  • Manipulation and configuration of online application at any time
  • No need to install specific software to access or manipulate cloud application
  • Online development and deployment tools to program runtime environment through PaaS model
  • Availability of cloud resources over the network to provide platform-independent access to all types of clients
  • Availability of on-demand self-service in order to use resources without interaction with cloud service providers
  • Highly cost effective due to its operation at higher efficiencies with greater utilities and the only requirement of internet connection
  • More reliability due to the use of load balancing method

Key terms

On-demand self-service: It allows the users to use web services and resources on demand so that one can log on to a website at any time and use them.

Broad Network Access: Cloud computing is completely web based therefore, it can be accessed from anywhere at any time.

Resource pooling: It allows multiple tenants to share a pool of resources enabling the user to share single physical instance of hardware, database, and basic infrastructure.

Rapid elasticity: Resources used by the customers or those which are currently assigned to the user are monitored automatically thus, making it easy to scale up or down the resources at any time.

Types of cloud computing services:  

cloud service providers

Infrastructure-as-a-service (Iaas)

This is the basic category of cloud computing. With Iaas, one can rent IT infrastructures like servers and virtual machines, storage, networks, operating systems from cloud provider on a pay-as-you-go basis. Using these service, consumers can control and manage the systems in terms of operating systems, applications, storage, and network connectivity, but are not given access to control the cloud infrastructure by themselves.

Platform-as-a-service (Paas)

It refers to those services which supply an on-demand environment for developing, testing, delivering and managing software applications. This service makes it easier for developers to quickly create web or mobile apps, without worrying about setting up for managing the underlying infrastructure of servers, storage, network, and databases needed for development. Also, while using this service, consumers can purchase access to the platforms which enables them to deploy their own software and applications in cloud. In this service, the operating systems and network access are not managed by the users and there are constraints on deploying applications.

Software-as-a-service (SaaS)

It is a method for delivering software applications over the internet, on demand, and on a subscription basis. Using these services, the cloud provider can host and manage the software application and underlying infrastructure. With this service, users can purchase the ability to access and use an application or service which is hosted in the cloud. A classic example of this is Salesforce.com, as mentioned earlier that the necessary information for the interaction between the user and the service is hosted as part of the service in cloud.

Deployment models

The use of cloud deployment models differs based on its requirement. There are four deployment models, each with specific characteristics which supports the needs of the services and the cloud users.

Private Cloud: It is a type of cloud computing which delivers scalability and self-service through a proprietary architecture. It offers hosted services to a limited number of people behind the security system and is dedicated to a single organization, thus minimizing the security concerns which some organizations have regarding the cloud. Besides this, the private cloud gives direct control over their data to the companies. In order to, reduce an organization’s on—premises IT footprint, Rackspace, and VMware cloud providers can deploy the private cloud infrastructure.

Community Cloud: The community cloud infrastructure is shared among several organizations who have similar interests and requirements. The operation may be in-house or with a third party on the premises, thus helps in limiting the capital expenditure costs for its establishment as the costs are shared among the organizations.

Public Cloud: Public cloud infrastructure is made available to the public on a commercial basis by a cloud service provider. It enables the user to develop and deploy a service in the cloud with very little financial outlay as compared to the capital expenditure requirements which are normally associated with other deployment options.

Hybrid Cloud: Hybrid cloud computing uses a mix of on-premises, private cloud, and third-party, public cloud services with orchestration between the two platforms. It allows workloads to move between private and public clouds as per computing needs and cost changes. Hybrid cloud gives greater flexibility and more data deployment options to the businesses.

Fundamentals of Cloud Computing

It is important to consider the business requirement and address the following issues, before deploying applications to cloud.

  • Data privacy requirement and data security
  • Budget
  • Type of cloud i.e., public, private or hybrid
  • Data backup planning
  • Training
  • Report requirements and dashboard planning
  • Client access planning
  • Data export planning

In order to meet all these requirements, it is necessary to have a well-compiled planning. The following diagram represents various phases to be practiced by an enterprise before migrating the entire business to cloud.

Hybrid cloud computing

Strategy planning phase: In strategy planning phase, we analyze the strategy problems which customers might face. The analysis is performed in two steps as follows:

Cloud computing value proposition

In this step, we analyze the factors influencing the customers while applying cloud computing mode and target the key problems the user wants to solve. Key factors involved in this step are as follows:

  • IT management
  • Cost reduction in maintenance and operation
  • Business innovation
  • Low cost outsourcing
  • High service quality outsourcing

Cloud computing strategy planning

In cloud computing strategy planning, a strategy document is prepared according to the conditions a user might face while applying cloud computing mode.

  • Cloud computing tactics planning phase

Cloud computing tactics planning phase performs the analysis of problems and risks in the cloud application to ensure the users that the cloud computing can successfully meet their business goals. There are four planning steps involved in this phase which are as follows:

  • Business architecture development

In business architecture development phase, we recognize the risks which might be caused due to cloud computing application from a business perspective.

  • IT architecture development

In IT architecture development, we identify the applications which support the business processes and the technologies required to support enterprise applications and data systems.

  • Requirements on quality of service development

Quality of service implies the non-functional requirements such as reliability, security, disaster recovery, etc., where the success of applying cloud computing mode depends on these non-functional factors.

  • Transformation plan development

In transformation plan development, we formulate all kinds of plans which are required to transform current business to cloud computing mode.

  • Cloud computing deployment phase

The cloud computing deployment phase focuses on both the cloud computing value proposition and cloud computing tactics planning phase. This phase involves the following two steps:

  • Cloud computing provider

This step involves selection of a cloud provider on the basis of Service Level Agreement, which defines the level of service the provider will be able to meet

  • Maintenance and technical service

These services are provided by the cloud provider along with ensuring the quality of services.

Cloud Computing Technology

In cloud computing, there are some technologies which work behind the cloud computing platforms to make it flexible, reliable, and usable. The technologies which are used are as follows:

Virtualization: It is the technique which allows the user to share single physical instance of an application or resource among various organizations or tenants. The processing of this technique is done by assigning a logical name to a physical resource and provide a pointer to the physical resource as per demand. The multitenant architecture offers virtual isolation among the multiple tenants thus, enabling the organizations to use and customize the application although they have their own instance running.

Service Oriented Architecture: Service Oriented Architecture assists to use applications as a service for other applications regardless of the type of vendor, product, or technology. Thus, it makes it possible to exchange data between applications of different vendors without additional programming or making excessive changes to services.

Grid computing: It refers to distributed computing in which a group of computers from multiple locations are connected with each other to achieve a common objective. An important thing to note in this case is that, these computer resources are heterogeneous and graphically dispersed. Notable feature of grid computing is that it breaks the complex task into smaller pieces and these smaller pieces are distributed to CPUs which reside within the grid.

Utility computing: This technique is based on Pay per use model and it offers computational resources on demand as a metered service. It is interesting to note that cloud computing, grid computing and managed IT services are based on the concept of utility computing.

Cloud Computing Architecture

Cloud computing architecture comprises of many cloud components which are all loosely coupled and can be broadly divided into two parts viz., front end and back end. Each of these ends is connected through a network which is usually done via the internet. The following diagram represents the graphical view of cloud computing architecture.

cloud technology

Front End: It refers to the client part of the cloud technology and consists of interfaces and applications which are required to access the cloud computing platforms like a Web Browser.

Back End: It refers to the cloud itself and consists of all the resources required to provide cloud computing services. Back End comprises of huge data storage, virtual machines, security mechanism, services, deployment models, servers, etc. It is important to note that, it is the responsibility of the back end to provide built-in security mechanism, traffic control and protocols. The server employs certain protocols which are known as middleware and they help the connected devices to communicate with each other.

Cloud Computing Infrastructure

Cloud infrastructure consists of storage, servers, network, management software, and deployment software and platform virtualization. Components of Cloud infrastructure are as follows.

Hypervisor: It is a computer code or low-level program which acts as a Virtual Machine Manager and it allows to share the single physical instance of cloud resources between several tenants.

Management software: It helps in maintaining and configuring the infrastructure.

Deployment software: It helps to deploy and integrate the application on the cloud.

Network: It is the key component of cloud infrastructure and it allows to connect cloud services over the internet. Also, it is possible to deliver network as a utility over the internet i.e., the consumer will be able to customize the network route and protocol.

Server: It helps to compute the resource sharing and offer other services such as resource allocation and deallocation, monitoring resources, security, etc.

Storage: Generally, Cloud is used as a distributed file system for storage purpose and if one of the storage resource fails, then it can be extracted from another one which makes cloud computing more reliable.

Cloud computing companies

There are many companies delivering services from the cloud and some of them are mentioned as follows:

Google: Google has a private cloud which is used for delivering many different services to its users, including e-mail access, document applications, text translations, maps, web analytics, etc.

Microsoft: It has “Microsoft Sharepoint”, an online service that allows the content and business intelligence tools to be moved into the cloud. Also, Microsoft is currently making its office applications available in a cloud.

Salesforce.com: Salesforce.com runs its application set for its customers in a cloud. Also, its products like Force.com and Vmforce.com provides the developers with platforms to build customised cloud services.

Characteristics of Cloud computing

Shared Infrastructure: Use of visualised software model enables the user to share physical services, storage, and networking capabilities. Regardless of deployment model. The cloud infrastructure seeks to make the most of the available infrastructure across a large number of users.

Dynamic Provisioning: It allows the user for the provision of services based on current demand requirements and is done automatically using software automation which enables the expansion and contraction of service capability as per requirement. While doing dynamic scaling, there is a need to maintain high levels of reliability and security.

Network Access: Computing needs to be accessed across the internet from a broad range of devices like PCs, laptops, and mobile devices using standard based APIs such as one based on HTTP. It is interesting to note that deployment of services in the cloud include everything from using business applications to the latest application on the newest smartphones.

Manage Metering: Computing uses metering for managing and optimizing the service and provides reporting and billing information. Thus, the users are billed for services according to how much they used these services during the billing period.

Thus, it can be inferred that cloud computing allows the sharing and scalable deployment of services as per the users need, from any location and the customer is billed based on the actual usage of these services.

Pros and cons of cloud computing

Benefits:

Cost saving: With optimum use of computing, companies can reduce their capital expenditures and use operational expenditures for increasing computing capabilities. It has a low barrier to entry but requires few in-house IT resources to provide system support.

Scalability/flexibility: Computing gives companies an option of starting with a small deployment and grow to a large deployment at a rapid pace and then scale back if required. The flexibility in computing allows companies to use extra resources during peak times, thus enabling them to satisfy consumer demands.

Reliability: Cloud computing services with multiple redundant sites supports the business continuity and disaster recovery ensuring that computing is reliable.

Maintenance: The system maintenance and access through APIs which do not require application installations onto PCs is done by cloud service provider. Thus, it reduces maintenance requirements to a large extent for the user.

Mobile accessible: Mobile workers have increased the productivity of system, due to accessibility in the infrastructure which is available everywhere.

Challenges

Cloud computing services

One of the drawbacks of cloud computing is that there may be a slowdown while delivering more services in the cloud but it can also provide opportunities, if these issues are resolved with due care and attention in the planning stages.

Security and privacy

Symbol cloud storage protect on white background (done in 3d)

Security and privacy are two of the most crucial issues surrounding cloud computing related to storing and securing data, also while monitoring the use of the cloud by the service providers. These issues generally result in slowing the deployment of cloud services. One thing to be assured about cloud computing, in this case, is that these challenges can be addressed by storing the information internal to the organization, thus allowing it to be used in the cloud. For this to happen, the security mechanisms between the organization and the cloud need to be robust and a hybrid cloud can be used to support such a deployment.

Lack of standards: Despite having documented interfaces, clouds have no standards associated with them and therefore it is unlikely that most clouds will be interoperable. With the Open Grid Forum developing an Open Cloud Computing interface to resolve this issue, the Open Cloud Consortium is working on cloud computing standards and practices. Currently, the findings of these groups are at a maturing stage, but it is still not clear whether they will be able to address the needs of the people deploying the services and the specific interfaces these services need.

Continuous evolution: User requirements are continuously evolving, as are the requirements for interfaces, networking, and storage which implies that a “cloud”, especially a public one should not remain static and needs to be continuously evolved.

Compliance concerns: The Sarbanes-Oxley Act in the US and Data Protection directives in the EU are among the two major compliance issues affecting cloud computing, based on the type of data and application for which the cloud is being used. In EU, there is a legislative backing for the data protection across its member states, whereas in US the data protection method is different and varies from state to state. This challenge results in Hybrid cloud deployment, with one cloud storing the data internal to the organization.

Cloud computing solutions

It can include IT infrastructure, development platforms, and software, although “cloud” can mean a lot of things to different people, but for IT professionals it offers a way to extend existing capacity and capabilities. Cloud services are essentially IT components like software, programming languages, networking and services that are delivered to organizations on-demand, usually on a pay-as-you-go or a subscription basis. Cloud service providers offers the organizations their utility type resources such as virtual machines, networking, and storage capacity. Cloud computing platforms are support structures meant to facilitate development environments using pooled and scalable resources. There are various software services which deliver applications using a multitenant architecture, since cloud resources can live both on and off premises or a combination of both, thereby employing a hybrid cloud model.

Cloud storage

It is a model of data storage in which the digital data is stored in logical pools, physical storage spanning multiple servers, and the physical environment which is typically owned and managed by a hosting company. These storage providers are responsible for keeping the data available and accessible, and the physical environment being protected and running. These storage services can be accessed through a co-located cloud computer service, a web service application programming interface (API) or by applications which utilize this APIs, such as cloud desktop storage, a cloud storage gateway, and the web based content management systems. Some of the notable features of a powerful, simple and cost effective cloud storage are as follows.

Durability: Google cloud storage is designed for a durability of 99.999999999% and it stores data redundantly with the use of automatic checksums to ensure data integrity. The user’s data is maintained in geographically distinct locations, with the help of multi-regional storage.

Availability: All storage classes offer very high availability leading to the accessibility of the data to the user whenever needed. Multi-regional storage offers 99.95% whereas regional storage offers 99.9% monthly availability in their service level agreement.

Scalability: Practically, the Google Cloud Storage is infinitely scalable and whether the user is supporting a small application or building a large exabyte-scale system, the cloud storage is capable of handling it.

Cloud hosting

These services provide hosting for websites on virtual servers which pull their computing resource from the extensive underlying networks of physical web servers. It follows the utility model of computing in which it is available as a service rather than as a product and is therefore compared with traditional utilities like electricity and gas. It exists as an alternative to hosting websites on single servers which can include either a dedicated server or a shared server and can be considered as an extension of clustered hosting, where the websites are hosted on multiple servers. However, with cloud hosting, the network of servers which are used is vast and often pulled from different data centers from different locations. Practical examples of cloud hosting can be considered under both the IaaS and PaaS classifications. Under IaaS offerings, the client is provided with the virtualized hardware resource on which they can install their own choice of software environment before building their web application whereas on a PaaS service, the client is also provided with the software environment on which they can go straight to installing and developing their web application. Businesses with complex IT infrastructures and experienced IT professionals may wish to opt for more customizable IaaS model but others may prefer PaaS option because of its easy operation. The deployment of cloud hosting for enterprise customers is the Virtual Data Center, which employs a virtualized network of servers in the cloud which can be used to host all the business’s IT operations which can include its website.

Another example of cloud hosting involves the use of public cloud models for hosting on virtual servers which pull resource from the same pool as other publicly available virtual servers and use the same public networks to transmit the data which is physically stored on the underlying shared servers which form the cloud resource. The public cloud includes security measures to ensure that the data is kept private and suffice for the website installation. In the situations where security and privacy is more of a concern, then businesses can turn towards cloud hosting in private clouds as an alternative for clouds which use ring-fenced resources irrespective of whether located on site or with the cloud partner. Following are the features and benefits of cloud hosting.

cloud computing example

Reliability: The website is hosted on a virtual partition which draws its resources like disk space from an extensive network of underlying physical servers. The benefit of such network is that, if one server goes offline, it dilutes the level of resource available to the cloud a little but without having any effect on the availability of the website whose virtual server will continue to pull resource from the remaining network of servers. It is observed that some cloud platforms can even survive an entire data center going offline, as the pooled cloud resource is being drawn from multiple data centers from different locations to spread the risk associated with it.

Physical security: As the underlying physical servers are housed within data centers, therefore, the benefit from the security measures are that these facilities after implementation will prevent people from accessing or disrupting them on-site.

Scalability and flexibility: The resource is available in real time on demand and is not limited to the physical constraints or capacity of one server. If a client’s site demands extra resource from its hosting platform because of spike in visitor traffic or due to the implementation of new functionality then the resource is accessed seamlessly. Even while using a private cloud model, the service can often be allowed to “burst” to access resources from the public cloud for non-sensitive processing due to the surges in activities on the site.

Utility style: In cloud hosting, the client only pays for what they actually use. Although, the resource is available for spike in demand, still there is no wasted capacity remaining unused in case of low demand.

Responsive load balancing: The software based load balancing enables instant scalability to respond to changing demands.

How Cloud Computing Works

One thing should be noticed that services provided by cloud computing work a little differently, depending on the provider. There are many who provide a friendly, browser-based dashboard which makes it easier for IT professionals and developers to order resources and manage their accounts. In order to give multiple options, some services are designed to work with REST APIs and a command-line interface.

Some of the common cloud computing example are Social networking sites like Facebook, LinkedIn, Myspace, Twitter, etc., web based email which is among one of the biggest computing services. Cloud computing e-mail solution allows the mechanics of hosting an e-mail server and maintain it to be taken out of user’s hand. This implies that one’s e-mail is accessible from anywhere. Some other examples include documents/spreadsheet hosting services, backup services, health care, government and banking and financial services.

Cloud infrastructure is a virtual infrastructure which is delivered or accessed via network or the internet. It refers to the on-demand services or products being delivered through the model which is highly automated computing resource complemented with storage and networking services, provided to the users. It is one of the basic product delivered by computing services through the IaaS model. With the use of this service, users can create their own IT infrastructure complete with processing, storage and networking fabric resources which can be configured in any way using a physical data center enterprise infrastructure. Cloud infrastructure includes virtual machines and components like virtual servers, virtual PCs, virtual network switches/hubs/routers, virtual memory, and virtual storage clusters.

Another concept which is related to cloud computing is the Cloud networking also called as cloud-based networking is used to describe the access of networking resources from a centralized third-party provider using WAN or the internet based technologies. In this type of networking, the network can be shared as well as used for cloud computing resources. In order to manage fewer customer devices with the network, it has spurred a trend of pushing more network management functions into the cloud.

cloud computing resources

A cloud application which is also known as cloud app, is an application program which functions in the cloud with the characteristics of both the pure desktop app and a pure web app. In case of a desktop app, it resides completely on a single device at the user’s location but doesn’t necessarily has to be a desktop computer while in case of a web app, it is stored entirely on a remote server and is delivered through a browser interface over the internet. Like desktop apps, cloud apps provide fast responsiveness and can also work offline. Also, cloud apps need not permanently reside on the local device, but they can be easily updated online. Therefore, these apps are under the constant control of users to prevent them from consuming large storage space on the user’s computer or communications device. Cloud apps can be used by anyone with a web browser and a communications device which can connect to the internet. Unlike a web app, cloud apps can be used on board an aircraft or in any other sensitive situation where wireless devices are not allowed since, the app will function even after disabling internet connection.

Deployment models:

  • Private cloud
  • Public cloud
  • Hybrid Cloud

Private cloud:

Private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party, and hosted either internally or externally. Undertaking a private cloud project requires a significant level and degree of engagement to virtualize the business environment, and requires the organization to reevaluate decisions about existing resources. When done right, it can improve business, but every step in the project raises security issues that must be addressed to prevent serious vulnerabilities. Self-run data centers[are generally capital intensive. They have a significant physical footprint, requiring allocations of space, hardware, and environmental controls. These assets have to be refreshed periodically, resulting in additional capital expenditures.

Public cloud:

A cloud is called a “public cloud” when the services are rendered over a network that is open for public use. Public cloud services may be free. Technically there may be little or no difference between public and private cloud architecture, however, security consideration may be substantially different for services (applications, storage, and other resources) that are made available by a service provider for a public audience and when communication is effected over a non-trusted network. Generally, public cloud service providers like Amazon Web Services (AWS), Microsoft and Google own and operate the infrastructure at their data center and access is generally via the Internet. AWS and Microsoft also offer direct connect services called “AWS Direct Connect” and “Azure ExpressRoute” respectively, such connections require customers to purchase or lease a private connection to a peering point offered by the cloud provider.

Hybrid cloud:

Hybrid cloud is a composition of two or more clouds (private, community or public) that remain distinct entities but are bound together, offering the benefits of multiple deployment models. Hybrid cloud can also mean the ability to connect collocation, managed and/or dedicated services with cloud resources. A hybrid cloud service crosses isolation and provider boundaries so that it can’t be simply put in one category of private, public, or community cloud service. It allows one to extend either the capacity or the capability of a cloud service, by aggregation, integration or customization with another cloud service.

Hybrid cloud adoption depends on a number of factors such as data security and compliance requirements, level of control needed over data, and the applications an organization uses.

Distributed cloud

A cloud computing platform can be assembled from a distributed set of machines in different locations, connected to a single network or hub service. It is possible to distinguish between two types of distributed clouds: public-resource computing and volunteer cloud.

  • Public-resource computing—This type of distributed cloud results from an expansive definition of cloud computing, because they are more akin to distributed computing than cloud computing.
  • Volunteer cloud—Volunteer cloud computing is characterized as the intersection of public-resource computing and cloud computing, where a cloud computing infrastructure is built using volunteered resources. Many challenges arise from this type of infrastructure, because of the volatility of the resources used to built it and the dynamic environment it operates in. It can also be called peer-to-peer clouds, or ad-hoc clouds.
Intercloud
The Inter cloud is an interconnected global “cloud of clouds” and an extension of the Internet “network of networks” on which it is based. The focus is on direct interoperability between public cloud service providers, more so than between providers and consumers (as is the case for hybrid- and multi-cloud).[

Multicloud

Multicloud is the use of multiple cloud computing services in a single heterogeneous architecture to reduce reliance on single vendors, increase flexibility through choice, mitigate against disasters, etc. It differs from hybrid cloud in that it refers to multiple cloud services, rather than multiple deployment modes (public, private, legacy).

 

IT roles in the cloud:

Let us consider the probability that management and administration will require greater automation, requiring a change in the tasks of personnel responsible for scripting due to the growth in code production. You see, IT may be consolidating, with a need for less hardware and software implementation, but it is also creating new formations. The shift in IT is toward the knowledge worker. In the new paradigm, the technical human assets will have greater responsibilities for enhancing and upgrading general business processes.

The Developer

The growing use of mobile devices, the popularity of social networking, and other aspects of the evolution of commercial IT processes and systems, will guarantee work for the developer community; however, some of the traditional roles of development personnel will be shifted away from the enterprise’s developers due to the systemic and systematic processes of the cloud configuration model.

Cloud computing provides an almost unlimited capacity, eliminating scalability concerns. Cloud computing gives developers access to software and hardware assets that most small and mid-sized enterprises could not afford. Developers, using Internet-driven cloud computing and the assets that are a consequence of this configuration, will have access to resources that most could have only dreamed of in the recent past.

The administrator

Administrators are the guardians and legislators of an IT system. They are responsible for the control of user access to the network. This means sitting on top of the creation of user passwords and the formulation of rules and procedures for such fundamental functionality as general access to the system assets. The advent of cloud computing will necessitate adjustments to this process since the administrator in such an environment is no longer merely concerned about internal matters, but also the external relationship of his enterprise and the cloud computing concern, as well as the actions of other tenants in a public cloud.

This alters the role of the firewall constructs put in place by the administration and the nature of the general security procedures of the enterprise. It does not negate the need for the guardian of the system. With cloud computing comes even greater responsibility, not less. Under cloud computing, the administrator must not only ensure data and systems internal to the organization, they must also monitor and manage the cloud to ensure the safety of their system and data everywhere.

To cloud or not to cloud:

Risk assessment

The main concerns voiced by those moving to the cloud are security and privacy. The companies supplying cloud computing services know this and understand that without reliable security, their businesses will collapse. So security and privacy are high priorities for all cloud computing entities.

Governance:

How will industry standards be monitored?

Governance is the primary responsibility of the owner of a private cloud and the shared responsibility of the service provider and service consumer in the public cloud. However, given elements such as transnational terrorism, denial of service, viruses, worms and the like — which do or could have aspects beyond the control of either the private cloud owner or public cloud service provider and service consumer — there is a need for some kind of broader collaboration, particularly on the global, regional, and national levels. Of course, this collaboration has to be instituted in a manner that will not dilute or otherwise harm the control of the owner of the process or subscribers in the case of the public cloud.

Bandwidth requirements

If you are going to adopt the cloud framework, bandwidth and the potential bandwidth bottleneck must be evaluated in your strategy. In the CIO.com article: The Skinny Straw: Cloud Computing’s Bottleneck and How to Address It, the following statement is made:

Virtualization implementers found that the key bottleneck to virtual machine density is memory capacity; now there’s a whole new slew of servers coming out with much larger memory footprints, removing memory as a system bottleneck. Cloud computing negates that bottleneck by removing the issue of machine density from the equation—sorting that out becomes the responsibility of the cloud provider, freeing the cloud user from worrying about it.

For cloud computing, bandwidth to and from the cloud provider is a bottleneck.

So what is the best current solution for the bandwidth issue? In today’s market the best answer is the blade server. A blade server is a server that has been optimized to minimize the use of physical space and energy. One of the huge advantages of the blade server for cloud computing use is bandwidth speed improvement. For example, the IBM BladeCenter is designed to accelerate the high-performance computing workloads both quickly and efficiently. Just as the memory issue had to be overcome to effectively alleviate the bottleneck of virtual high machine density, the bottleneck of cloud computing bandwidth must also be overcome, so look to the capabilities of your provider to determine if the bandwidth bottleneck will be a major performance issue.

Financial impact

Because a sizable proportion of the cost in IT operations comes from administrative and management functions, the implicit automation of some of these functions will per se cut costs in a cloud computing environment. Automation can reduce the error factor and the cost of the redundancy of manual repetition significantly.

There are other contributors to financial problems such as the cost of maintaining physical facilities, electrical power usage, cooling systems, and of course administration and management factors. As you can see, bandwidth is not alone, by any means.

Mitigate the risk:

Consider these possible risks:

  • Adverse impact of mishandling of data.
  • Unwarranted service charges.
  • Financial or legal problems of vendor.
  • Vendor operational problems or shutdowns.
  • Data recovery and confidentiality problems.
  • General security concerns.
  • Systems attacks by external forces.

With the use of systems in the cloud, there is the ever-present risk of data security, connectivity, and malicious actions interfering with the computing processes. However, with a carefully thought out plan and methodology of selecting the service provider, and an astute perspective on general risk management, most companies can safely leverage this technology.

So this was all about the cloud computing definition, its services, companies, advantages and disadvantages, if you have any query regarding the post or anything else, you can leave a comment below we will reply to you at the earliest.

Disadvantages of Cloud Computing

Cloud computing is a boon to today’s world for everyone, but still there are some disadvantages of cloud computing, so let’s know all of those.

In Cloud Computing, the word “Cloud” is used as a metaphor for the internet and therefore the phrase “Cloud Computing” implies a type of internet based computing. In this type of computing, there are different services provided which include servers, storage, and applications that are delivered to an organisation’s computers and devices through the internet. It is an on-demand service which has obtained mass appeal in corporate data centres and it enables the data centre to operate like the internet and computing resources to be accessed and shared as virtual resources in a secure and scalable manner.

disadvantages of cloud computing

Limitations of Cloud Computing

Cloud computing has although benefited many enterprises by reducing costs and allowing them to concentrate on the core business competence they are in rather than IT and cloud infrastructure issues. For all the generally well earned hype, there are still few distinct disadvantages of Cloud Computing, especially related to smaller operations, that one should consider before taking the leap.

Drawbacks of Cloud Computing

  • Downtime

This is among one of the worst disadvantages of cloud computing and no cloud provider, even the very best could claim immunity to service outages. Cloud computing systems are internet based which implies that the access to it is fully dependent on the internet connection. It should not be thought that one’s business can absorb prolonged bout of frequent outages or slowdowns. For example, in 2014 there few incidents where service providers like DropBox faced an outage for as long as two days.

The two key points to be considered in such situations are by asking two questions. Firstly, which business processes of yours can be delayed or halted if the service provider goes down? And secondly, when the internet connection is down, does your applications drop offline? The best practice for minimizing planned downtime in an SAP environment is to demand a service level agreement from your provider, guaranteeing uptimes more than 99.55% which is equivalent to 1.83 days of downtime a year or 3.6 hours of downtime a month. Below are some of the challenges of cloud computing.

  • Cloud Computing Security and privacy
Symbol cloud storage protect on white background (done in 3d)

It is essential that all the discussions related to data must address security and privacy, especially while handling or managing sensitive data. The case of Code Space should always be remembered and what happened to it after its AWS EC2 console was hacked and its data got eventually deleted and then the company was forced to close the doors forever. An important point to note is that by leveraging a remote cloud based infrastructure, a company outsources everything it has, though your cloud service provider is expected to manage and safeguard the underlying hardware infrastructure of a deployment, the remote access is your responsibility and in most of the cases no system is perfectly secured. Therefore, it becomes critical to carefully weigh all the risk scenarios.

  • The privacy of the cloud based data is a doubt after the recent leaks of celebrity pictures and countless millions of user login credentials. Thus, it becomes important to be specific about the questions regarding the trust on your service provider and will you be able to face it, which are among the riskiest disadvantages of cloud computing.

Steps to minimise security and privacy risks are as follows.

  • Know all the people who are supposed to have access to each resource and service
  • Limit data access on the basis of user extent context
  • Involve in a risk based approach for securing assets used in the cloud
  • Extend security to the devices and add intelligence to network protection
  • Build the ability to see through the cloud
  • Vulnerable to attack

Every component in cloud computing is potentially accessible from the internet and there is nothing connected to the internet which can be considered to be perfectly secured, even the best teams suffer severe attacks and security breaches. Cloud computing is built as a public service and it is considered as the saying goes it is easy to run before you learn to walk. Also no one at AWS checks your administration skills before granting you an account as it only considers a valid credit card to get started.

Steps to minimise cloud attacks to help your organisation to monitor the exposure and critical data movements are as follows.

  • Identification of threat by correlating real-time alerts with global security intelligence
  • Protect your information proactively
  • Automation of security through IT compliance controls
  • Prevention of data exfiltration
  • Integration of preventive and responsive strategies into security operations
  • Discover rogue projects with audit and authenticate identities
  • Limited control and flexibility

Cloud users have limited and varying control over the function and execution of their hosting infrastructure. Cloud provider’s end user license agreement and management policies might impose limits on the ability of customers handling their deployments. Except for the backend infrastructure, customers are limited to the control and management of their applications, data, and services. None of these are going to pose the problem to the user, but for the security purpose, these factors need to be considered.

  • Dependency of cloud computing platforms

Another disadvantage of cloud computing is the implicit dependency which is also known as vendor lock-in. Major differences between vendor systems can sometimes make it impossible to migrate from one cloud platform to another. An important thing to note is that it is not only complex and expensive to reconfigure the applications to meet the requirements of a new host, but migration can also expose your data to additional security and privacy vulnerabilities. To decrease the problems associated with dependency, it is important to properly understand what the vendors are selling and can it help in avoiding lock-in problems in the cloud. In many cases, it is observed that knowing what is going on and planning for it can make a big difference.

  • Cost of cloud computing

On a small scale and for short term projects, cloud computing can be a costly thing. Despite trying to reduce staff and hardware costs, the overall price tag could end up higher than the expectation. Before being sure of what will work best for you, it is always preferred to experiment with the variety of offerings. Also, it is possible to make use of the cost calculators which are made available by the providers like Amazon’s AWS and Google’s GCP.

Steps to reduce cloud computing cost are as follows.

  • Scale down as well as up and pre-pay, only if you have a known minimum wage
  • Stop your instances for unused services
  • Watch out for cloud sprawl
  • Set smart alerts and make the cost proxy for usage

Despite the above disadvantages of online storage, the environment has immense potential for many business models and as the platform matures and economies of scale continue to grow, costs will start to fall and reliability and security standards will improve.

Cloud Computing Disadvantages: Cloud Storage

cloud storage

Talking about the other side of this, the following are the advantages of cloud computing.

As technology is moving forward people are adapting those at such a pace that was not expected. There was a time when people use to store digital files in floppy, then came the disk, pen drive and hard disk. Now they prefer to store file online and this storing file online and sharing is the simplest form of Cloud computing. So according to Wikipedia “Cloud computing is a type of internet-based computing that provides shared computer processing resources and data  to computer  and other devices on demand”. As the whole process of cloud computing is adapted by firms as well as others in this article we would be talking about the disadvantages of cloud computing.

First thing that any business wants is how they can reduce cost so as a benefit of cloud computing it provides us with the flexible cost. It is possible because the all that it needs is server a bit of infrastructure so when demand goes up more space can be used and once demand gets normal the space can be de-provisioned. Rather than in traditional way we need to buy capacity that could be sufficient for the peak time so for the rest of the time space goes ideal thus waste of money. Before they begin they need to spend lots of money on buying lot of equipment, build, and operate data Centre, buy hardware, facilities and things that would be required to run it. All this money is spent and they not even earn a value for it for a long time.

Taking an example of cloud computing so suppose Firm X that has the option is to either reduce the size of their service Centre if they already have and they can also remove all of it. Opting either of the option will reduce the cost of servers, software purchase and staff still the firm would be working in the similar manner as it was working earlier.

After saving the money by reducing cost another reason for why cloud computing is ease in managing. As in cloud computing whole thing is managed by central server so there is no need of maintenance of main server and rest things like updates are provided by the service provider. All you need to do is, things like copying file from any pen drive only thing different is that here you will be using web interface which doesn’t even need to be installed so it won’t be using any of your space.

One question that may arise in your mind is are that software always available? So, the answer is yes so availability also adds up to the advantage of cloud computing. Cloud service provider are so reliable that their system is up 99% of time. Unless your own internet is working they are almost ready to serve you also some of their software work offline. Also, access is not restricted through your desktop or laptop it can be done through any device such as mobile phone and tablet. Location does not restrict cloud it is accessible from any location so cloud computing is mobile and these acts as benefits of cloud computing.

Cloud computing provides us with the opportunity to work with someone who is physically too far from us. As all of things can be shared there on the cloud then group of people from different location can simultaneously work on the same thing and share information with each other at real time. Similarly, this could also work in favor of two firm in case of merger and acquisition as all they need to do is share the data that is already present on the server. Traditionally they need to decommission data Centre and migrate and this whole process would take few year.

In business one thing that is most important is staying in front of competitor, so companies using cloud computing can have edge as they don’t have to worry about procurement, so no upfront cost and the firm can focus on their core business strategy and objective instead of worrying about the technology as these things are taken care by the firm that is providing cloud service.

In current business CSR and saving environment also act the important part so how does cloud computing benefits the firm here. As discussed above in the article use of cloud computing could reduce the number of data Centre also firms would be sharing their resources thus it would have less impact on the environment.

Till now in this article we have discussed the pros of cloud computing but there no such thing who is tilted on one side every positive has its negative. Similarly, in cloud computing we may have security issue as whole data is shared on same platform. By any chance if a hacker manages to hack a server thought the intention of that one is to get another information but along with that he is able to get extra things. Also, if you are using someone else’s server then you might have to provide them with important business data.

Previously in pros we have discussed that server is up 99% of time but this 1% of time down can lead to loss of millions of dollars. As you won’t be able to access any information that is stored there and all the business activities must be suspended for that time. We also discussed that in case of Merger and Acquisition firms using cloud computing must do was just share the data but in case of software there are still few of them that is fully functional on cross platform. For example, some software that is made for windows might not work on Linux or IOS.

Opting for cloud computing may also lead to loss of control or minimal control as all the things whether it’s about some software or platform all of these things are handled by the service provider. So, the firm or customer can only have a control on the service that is operated on that platform of software like the data that they store.

 Performance interference and noisy neighbors

Due to its multi-tenant nature and resource sharing, cloud computing must also deal with the “noisy neighbor” effect. This effect in essence indicates that in a shared infrastructure, the activity of a virtual machine on a neighboring core on the same physical host may lead to increased performance degradation of the VMs in the same physical host, due to issues such as e.g. cache contamination. Due to the fact that the neighboring VMs may be activated or deactivated at arbitrary… times, the result is an increased variation in the actual performance of cloud resources. This effect seems to be dependent on the nature of the applications that run inside the VMs but also other factors such as scheduling parameters and the careful selection may lead to

This effect seems to be dependent on the nature of the applications that run inside the VMs but also other factors such as scheduling parameters and the careful selection may lead to optimized assignment in order to minimize the phenomenon. This has also led to difficulties in comparing various cloud providers on cost and performance using traditional benchmarks for service and application performance, as the time period and location in which the benchmark is performed can result in widely varied results. This observation has led in turn to research efforts to make cloud computing applications intrinsically aware of changes in the infrastructure so that the application can automatically adapt to avoid failure.

Data Breaches

In the Notorious Nine report, the CSA notes, “It’s every CIO’s worst nightmare: the organization’s sensitive internal data falls into the hands of their competitors.” Cloud computing has introduced new avenues for cyber attacks and putting data at risk. Of course, there are ways to prevent data loss and strengthen data security, but it’s a double edged sword. Encryption protects data at rest, but lose the encryption key and you’ve lost the data. The cloud routinely makes copies of data to prevent its loss due to an unexpected die-off of a server. The more copies, the more exposure you have to breaches.

Data Loss

The prospect of seeing your valuable data disappear into the ether without a trace can leave you skeptical to use cloud services. The data loss can happen in a variety of ways: It can occur when the owner of encrypted data loses the key that unlocks it; A malicious hacker might delete a target’s data out of spite; or, you could lose your data to a careless cloud service provider or a disaster, such as a fire, flood or earthquake.

Account or Service Traffic Hijacking

Should a hacker gain access to your credentials, they will be able to monitor your activities and transactions, manipulate data, and redirect clients incorrectly.Your account or services instances may become a new base for the attacker. From here, they may leverage the power of your reputation to launch subsequent attacks.

Insecure Interfaces and APIs

IT administrators rely on interfaces for cloud provisioning, management, orchestration and monitoring. APIs are integral to security and availability of general cloud services. From there, organizations and third parties are known to build on these interfaces, injecting add-on services. This introduces the complexity of the new layered API; it also increases risk, as organizations may be required to relinquish their credentials to third parties in order to enable their agency.

Denial of Service

DoS has been an Internet threat for years, but it becomes more problematic in the age of cloud computing when organizations are dependent on the 24/7 availability of one or more services. DoS outages can cost service providers their customers and prove to be pricey to customers who are billed based on compute cycles and disk space consumed.

Malicious Insiders

Any number of supposed allies can gain access to a network, system or data for malicious purposes — from a current or former employee, a contractor, or a business partner who wishes to do harm to data. In an improperly designed cloud scenario, a malicious insider can wreak even greater havoc. In situations where a cloud service provider is solely responsible for security, the risk is great. Even if encryption is implemented, if the keys are not kept with the customer and are only available at data-usage time, the system is still vulnerable to malicious insider attack,

Cloud Abuse

“It might take an attacker years to crack an encryption key using his own limited hardware. But using an array of cloud servers, he might be able to crack it in minutes,” the report noted. Another example might be a malicious hacker using cloud servers to launch a DoS attack, propagate malware or share pirated software. The issue is that responsibility for use of cloud services rests with service providers. Therefore, they must be the ones to constitute what is cloud abuse and what isn’t, as well as developing best practices in preventing it.

Insufficient Due Organisations

anizations that embrace the cloud without fully understanding the cloud environment are at a substantially higher risk than those who do have an understanding.

Shared Technology

Cloud service providers share infrastructure, platforms and applications to deliver their services in a scalable way. So, one of cloud computing’s biggest assets can, in turn, become a liability. “Whether it’s the underlying components that make up this infrastructure (e.g. CPU caches, GPUs, etc.) that were not designed to offer strong isolation properties for a multi-tenant architecture (IaaS), re-deployable platforms (PaaS), or multi-customer applications (SaaS), the

So now as we have discussed all the pcons of cloud computing it’s upon you whether to go for it or not. Though pros seem to be on the higher side due to its low cost, easy management but we cannot ignore the cons such as privacy and security. The decision all matter on what is valued more and what can be most beneficial for an individual.

How does Cloud Computing Work?

Before we move forward and dig into that how does cloud computing work, first let’s understand the concept and meaning of the term “cloud”. Whether you want to become a cloud engineer or you are a fresher who wants to learn all the basics of cloud computing then the post is meant for you. Sometimes to be referred as the “cloud”, cloud computing is a way or technique for the companies as well as individuals to access the digital resources over the internet and that too from anywhere in the world. In cloud computing, information and data is stored on the physical or virtual servers that are maintained as well as controlled by the cloud provider, for example, Amazon and their AWS product. In simple terms,  cloud computing is an emerging trend nowadays of the online file access that is being used by the businesses and individual worldwide.

 how does cloud computing work

By using the centralized server, expenses can be minimized as it directly eliminates the need to buy various software and also hardware that is needed to run the local servers. Clouds can be private that limits the access to the servers to a specified group and public which can be accessed by any user that logged onto the internet or the virtual public, where the private cloud of the services can be easily attained by using resources of public. For taking advantage of cloud computing one of the most important requirement is high speed internet. There are different types of services that are offered by the cloud computing listed as follow:

  • Software as a Service (SaaS) In this type of service, registered software applications are all managed by the provider. Another browser-based access allows individual applications that to be used by the customers even without bothering about server expenses or licensing issue.
  • Platform as a Service (PaaS): In this service, provider manages the working platform to run and develop the business applications. It is build so that to support all the stages of creating the web application online, without the additional software that are needed in the local computers.
  • Infrastructure as a Service (IaaS): This service of cloud computing can be referred as the enhanced version of the web hosting. Virtual servers with the related data as well as equipment can be easily purchased on the per use basis.

Even though the end user in the cloud computing doesn’t require to get worried about installing and managing all the applications which they don’ know how works, this approach still have some of the drawbacks. So now you will aware that the end user don’t get the control over any software terminal from the cloud, and in real only the side you need will be provided to you. Now let’s understand the idea of cloud computing working.

The idea is basically based on the rehash of the Distributed System. Now imagine simply a client-server relationship in any company. The server is meant for storing the data and programs. The client (employees for this case) access the server to get the data whatever they actually need. So, if we consider server room of the cloud computing company as the Back End where installation, updates, and log processing part is going on, the front end will be the client’s computer that runs on what you need is what you see basis.  The client doesn’t require to take care of the server issues, what he do is simply ask to work on some of the particular programs and get the job done and this is what the server provides. So cloud is nothing but a collection of the virtual computers which contains the certain resources on the giant server farms that a user can access easily. Once you get all the idea of how the structure of a simple client and server database works, all you need to do then this add to it to the internet.

Back End

The cloud is the collection of all data such as software, apps, storage, that a user can subscribe for and access it at any time by using the internet. Here the backend is like multiple servers which work together each one of them holding the app or a software. This means that the software or the app belongs to the dedicated server. And further, all these dedicated servers are controlled as well as managed by the administrator server. The data that will be stored here will most likely to be encrypted and password protected as well along with the other security levels. Backend’s storage room size depends on number of clients and whether the company is actually going to provide the backup data for the client.

Front End

The front end can be referred as the customer/client end of the cloud. The user here approaches to the cloud service provider to subscribe to all their packages. Anytime she/he requires to access the file or run the software or app, the request is accepted by the cloud. It connects to the relevant server and that too in no time, and then you get the app right on your screen.

How does Cloud Computing work?

How does Cloud Computing work

There are so many servicer providers from where you can easily subscribe to such as Amazon web services or Verizon/Terremark or IBM. Once you get subscribed to that then whenever you need to access to a particular software at that time you just need to log in through the internet and just select the software.  One of the important thing that is best for its customers is that you don’t need to download or install anything. Whatever you want to use you just need to do it on the cloud, not on your computer. This also eliminates the cost of downloading the software. You just only need to pay for the service that you use. Updates are no longer for your concerns. This is a most important aspect of the cloud computing as multiple users will be working on the same project but with the different versions of the software and making update can create conflict in the process. The same is applicable to the individuals that are using different operating systems (PC, Linux or Mac). So consider if someone starts a tutorship or they put their entire learning as the modules on cloud system then anyone can access it, access the videos, chat to the professors and much more. This will be very different from the regular e-learning as now you don’t require to go somewhere or install anything and can take advantage of flexible learning routine.

So it will not be wrong to consider it as the combination of the one-way grid computing (data transfer between the client and server only) with the utility computation. A company makes a cloud that a client/user pays for to use it wisely.  This is the very basic principle of such type of servers.

Common Examples of Cloud Computing Tech

Cloud computing seems to be a foreign or new concept there is nothing like that as you actually use it in your daily life but you don’t realize it. So here are some of the familiar tasks that are possible through the cloud computing.

  • Checking your email from anywhere in the world by logging on to the cloud-based webmail client.
  • The second thing that you might do on regular basis is saving the document in the online cloud storage account and after sometimes accessing it at work when required, even though when the original file also resides in your home computer.
  • Collaborating with colleagues in a real on the shared spreadsheet that are actually working from the different location.
  • It also allows you to rent the software applications and then save all the documents that you create online, rather than purchasing physical software disks and download the contents to your own hard drive.

What makes Cloud Computing different?

Its management

The service that is used here by you is provided by someone else and it is also managed for you by someone else on your behalf, how exciting it is as you don’t need to take care of anything rather than just using it efficiently. Like if you are using Google documents you don’t need tow worry about buying the license for the word processing software or to update it on the monthly or yearly basis. Also, you don’t need to take care or worry about the viruses that can affect your computer or create backup of the files, google does all this for you. This is same for the cloud computing also.

It’s on demand

Cloud Services are provided on the basis of available demand and is bought on a “pay as you go” or on the subscription basis. So cloud computing can be bought same as you buy the electricity telephone services or the internet access from the utility company.

Public or Private

Cloud computing comes with the two aspects of its services public as well private as per the requirement of the user. These can be said as the cloud equivalents of the internet or the intranet.

Pros and Cons of Cloud Computing

Like any other technology, cloud computing also has some of the good as well as bad attributes. So let’s go in depth and find out some of the advantages and disadvantages of the Cloud Computing.

Reduced Need for the on-site IT staff

With cloud computing the on-site IT staff requirement is minimized to a good level. As if you have chosen a service provider for your cloud computing needs, then you must have noticed that most of them will guarantee you a high level of the consistent uptime.

Cost Effective

As already mentioned above, cloud computing provides you the advantage to buy only that cloud services that you actually need, and also have the option of scaling it up when found necessary. So this means that you don’t require to make large investments that on the physical equipment that might get stolen or breaks down.

Fewer maintenance concerns

While dealing with the physical computer networks, hardware and software part, there is a lot of maintenance that all of them require from your side. So it is the critical as well as costly responsibility to take care of the maintenance of this hardware as well as software parts on regular basis.  And with the cloud computing, you need to worry any of the above issues, maintenance or update.

Internet Requirement

There is a requirement of internet connectivity if one needs to take advantage of cloud computing. So it can be the issue if your internet connection is poor, at that time you won’t be able to access the files efficiently.

Migration Issues

If you have started using one cloud computing service and now then want to transfer the files over to some different provider then this process can proved to have a hectic and complicated one. Whereas the process will make the task bit easier but still some of the substantial incompatibility issues can make the process of moving the files between both the providers a bit difficult.

Less Customer Control

Cloud computing also offers the managed service which means that the customers give up the control over what is offered to them.As many of the service providers don’t provide details about their infrastructures to their customers and meanwhile prefer to handle the administration needs on their own.

How does Cloud Computing work

With that such broad range of the services provided by the cloud, most of the different organizations, as well as individuals, can benefit from leveraging its own power. By working on the principle of remotely sharing and aggregation of the processing power as well as processes, the cloud provides a unique method for all its customers who really want to access the dynamic and high-performing hardware and the software solutions. So with so many services and advantages, some minor disadvantages can be ignored of the cloud computing as it has so much to offer to its customers. Also in coming future cloud will be one of the prominent cloud computing technology from which everyone takes benefit from. So this was all about how does the cloud work, its services and benefits. If you have any query regarding the post you can leave a comment below we will reply to you at the earliest.

Top 50 Cloud Computing Companies

Cloud computing companies are sprouting up faster than flowers in springtime. The surest sign of a new industry is a plethora of startups, and that is certainly the case in the cloud computing industry. But after cloud computing’s first decade, there are two distinctly different truths – regardless of whether you’re talking about public, private, or hybrid cloud offerings. First, the inevitable consolidation has not taken place. Sure, big firms have snapped up small players, but many cloud startups are still in growth mode and not looking to be bought. Second, the presence of old school tech giants in cloud computing. Established firms are often the last to embrace a technology, or at least very late to it. They are so enamored to their current business model that there is no room for embracing a new one – or they fear the new model because it could disrupt their current business.

That’s not the case here. In our list of the 50 leading cloud computing companies, you will see big names that have been around for decades. They recognized the new trend got on board, even if not in the first wave.

Amazon Web Services | How to install AWS

It has been 11 years since the launch of Amazon groups its Infrastructure as a Service offering  (IaaS) In 2006 Amazon Web Services (AWS) began offering IT infrastructure services to businesses in the form of web services now commonly known as cloud computing. Today the service AWS is the one which consists of Storage and Content Delivery, Computing, Database and Networking.  It is a much reliable product when It comes to looking for a complete and balanced private infrastructure a group would wish for.  The services include AWS Identity Management, Amazon Cloud Services, AWS Identity Management, AWS Certificate manager for managing SSL/TLS certificates, also hardware-based key storage and management with AWS CloudHSM.

Services offered by Amazon Cloud Computing

Amazon Cloud Services

Monitoring over your infrastructure has never been easier with the use of these management tools by AWS like AWS Cloudtrail, Amazon CloudWatch and AWS Config for tracking resource inventory and changes. AWS has been in the cloud business since 2006 making it the oldest and most stable one in the business.  Its vast list of associated services made it much larger with it’s even better list of value-add partners who allows you to build exactly the kind of infrastructure that’s right for your organization. it could be cloned,  set private IPs, load-balanced, pluggable cloudy disks (EBS) and many more features that any development team would need to build their targeted application. It is the most generic and portable way to host a web application starting from cloud database to e-commerce storefronts, all in one place with custom coded apps. One can feel like a powerful server admin without having to uphold any physical structure or manage machines and instances within a click. A cloud service such as Amazon Web Services owns and maintains the network connected hardware necessary for these application services, while anyone provision and use what you need via a web application.

Cloud computing offers developers and IT departments with the freedom to focus on priority and avoid undifferentiated factors such as procurement, maintenance, and capacity planning. Since cloud computing has grown over time, several different models and deployment strategies have developed to help meet specific needs of different users.
Infrastructure As a service consists of the basic building blocks of for a cloud and technically provides access to networking features such is Amazon Web Service.

Features of Amazon Web Services

Features of Amazon Web Services

The four main offerings  Storage and Content Delivery, Computing, Database, and Networking can be controlled at a higher level with extensive admin controls accessible via a secure Web client.
Compute:   Designed to make web scaling easier for web developers  Amazon Elastic Compute Cloud (Amazon EC2) provides secure, resizable compute capacity. It decreases the time required to obtain and boot new server instances up to minutes providing you quicker scale capacity as your computing requirement changes. You need to pay only for the capacity you actually use and also provide a build failure resilient applications.

Benefits of EC2:  completely controlled instances, integrated with services like Amazon simple storage service and relational database service, highly reliable environment where replacement instances, secured in combination with Amazon VPS.
The computing services by Amazon also includes container management service Amazon EC2 Container Service (ECS) that support docker containers. Amazon EC2 Container Registry (ECR) another fully managed Docker container registry that makes it easy for developers to store, manage, and deploy Docker container images. Amazon Lights trail  for the launch and management of servers, AWS batch to easily run thousands of batch computing jobs, AWS Beanstalk, AWS Lamda and also Auto scaling.

Pricing:   Amazon EC2 is free to try , also with three ways to pay for EC2 :
1. On-Demand: One can pay for computing capacity at the hour basis with no long-term commitments or upfront payments. Depending on the demand the capacity could be adjusted i.e. increased or decreased.
Recommended for:  Users that prefer low cost and flexibility of Amazon EC2 without any up-front payment, short-term applications, unpredictable uninterrupted workloads.
2. Spot instances: Usually available at a discount when compared to the On-Demand pricing range, one can reduce the cost of running the applications, grow its compute capacity and throughput at the same budget, and enable new types of cloud computing applications.
Recommended for:   Applications with flexible start and end times, apps that are only feasible at very low compute prices and users with urgent computing needs.

3. Reserved Instances:  Provides up to 75% discount when compared to the on-demand pricing range, it is assigned to a specific availability zone wherein a capacity reservation is provided, providing an additional service to launch instances whenever needed.
Recommended for: Apps with steady state usage, apps that may require reserved capacity.
Storage: Storage with a simple web service interface to store and retrieve any amount of data from anywhere could be done by using  Amazon Simple Storage Service (Amazon S3). It can be used as a primary storage for cloud-native applications for analytics.
Benefits of S3 : It is simple to be used with a mobile app as well, provides full REST APIs and SDKs for easy integration, designed for durability of 99.999999999% of objects, secured with data transfer over SSL and automatic encryption, Integrated with other AWS services and Simple data transfer benefits with cloud data migration.

The storage services also come with Amazon Elastic bookstore ( Amazon EBS ) which provides constant block storage volumes in conjunction with Amazon EC2 instances in AWS Cloud. Amazon EBS volumes offer the reliable and low latency performance needed to run high workloads with a choice of choosing between solid-state disk (SSD)-backed or hard disk drive-backed (HDD )volumes.
A few more services from the storage category include Amazon Elastic File System (Amazon EFS) for scalable file storage that can create an configure file systems quickly and easily.

Database


Database
:  Amazon Aurora provides better performance than MySQL with a compatible relational database engine. It ia high in performance and provides 5x the throughput of standard MySQL and twice the throughput of standard PostgreSQL.
Benefits of Amazon Aurora: Provides multiple levels of security including nework isolation with Amazon VPS, one can create controls using AWS key management services,. One of the best benefits of Amazon Aurora is that it is fully compatible MySQL 5.6 using the InnoDB storage engine which makes Amazon Aurora compatible to your current tools of MySQL database. IT is highly scalable and automatically grows storage as needed, from 10GB up to 64TB. The storage is fault-tolerant, self healing also provides the service of copying your data six times and replicate across three availability zones with a persistent backup to Amazon S3.

There is nothing that makes it easier than Amazon Relational Database Service (Amazon RDS) to launch, operate and scale a relational database in the cloud, it provides you with the freedom while managing time-consuming database administration work and lets you focus n your target business. There are six common database engines one can choose from: Amazon Aurora, MySQL, Oracle, PostgreSQL, Microsoft SQL Server and MariaDB.

Benefits of Amazon RDS: No necessary requirement for infrastructure provisioning, the WS RDS Command Line Interface can be used to access the capabilities of a production ready relational database within minutes. One can scale the database’s computer easily. If conditioned with a Multi-AZ DB instance, Amazon RDS synchronously replicates the data to a standby instance in a different Availability Zone (AZ) and enhances reliability for critical production databases. It is secure with easy connect to the database also lets you run the instances on Amazon VPS, provides encryption at rest and encryption at transit.

A database that supports both document and key-value data models is Amazon DynamoDB, with a quick and NoSQL database service. With a reliable performance, it is a great choice for gaming, mobile app Internet of things (IoT).

Benefits of Amazon DynamoDB:  It is fast and constantly provides better performance as your data volume grows. This product uses automatic partitioning and SSD technologies for your throughput needs and delivers low latencies at any scale. In any case, your throughput needs change you can easily update your table’s request capacity using the AWS Management Console or the Amazon DynamoDB  APIs.  No requirement of managing database tasks such as setup, configuration, hardware or software provisioning since Amazon DynamoDB is itself fully managed. It integrates with AWS Lambda to provide Event-driven programming which enables you to build applications that quickly react to any data change. Amazon DynamoDB also combines with AWS IAM for your colleagues to provide fine-grained access control.

 Amazon ElastiCache

An in-memory cache service product is Amazon ElastiCache, it helps to improve the performance of web apps by retrieving information from quick, managed, in memory caches, rather than relying completely on slower disk-based databases.It currently supports two open sources in memory caching engines.
Redis: Provides ease of use with availability, reliability and exactly needed performance for demanding apps. Enabling scalability to up to 3.55 TiB of memory data it is ideal for gaming, mobile app, ad-tech and also IoT.
Memcached: It is a memory object caching system, which works flawlessly with this service.

Networking and Content Delivery:  Most important of all at AWS is Amazon Virtual Private Cloud (Amazon VPC) allows us a condition to logically isolate the section of the AWS Cloud where we can launch AWS resources in a virtual network. It provides absolute control over virtual networking environment with a part of own IP address range, the configuration of route tables and also network gateways. One can youse IPv4 and IPv6  on the VPC for safe and simple admission to resources with customized network configuration. Here, they have also provided multiple layers of security with security groups and network access control lists. A hardware virtual private network (VPN) can also be created to incorporate connection between data center and VPS  and control the AWS cloud as an extended corporate data center.

Another popular global content delivery network is Amazon CloudFront which integrates with other AWS products and services to provide the teams a freedom of content delivery to end users, with no minimum usage commitments. This product can be used to bring an entire website, including dynamic, static, streaming and interactive content by a global network of edge locations.  It can be used with other services such as Amazon S3, Amazon EC2 yet also works seamlessly with the non-AWS origin server.

A highly available and scalable cloud Domain Name System (DNS) web service is Amazon Route 53, provide developers an enormously dependable and cost effective method to route the end users to Internet applications by translating human readable names to numeric IP addresses that systems would use to connect to one another.  The cloud domain name system by Amazon AWS would efficiently connect user requests to infrastructure running in AWSsuch as EC2 instances, Elastic Load Balancing load balancers, or Amazon S3 buckets and also could be used to route users to infrastructure outside of AWS. With the use of Amazon Route 53 traffic flow’s easy visual editor, one can effortlessly manage their end-users which are routed to their application’s endpoints whether in a single AWS Region or distributed at any part of the web. Amazon Route 53 also provides Domain Name Registration that one can purchase and direct domain names such as sampleuse.com and Amazon Route 53 will routinely configure DNS settings for the domains.

If you need to put terabytes or even a petabyte of data into the cloud, then AWS Snowball it is.  The utilization of Snowball focuses common challenges with large scale data transfers with high network costs, long transfer times and security concerns. Transferring data with Snowball is simple, fast, secure, and can be very less as a cost of high-speed Internet. Snowball encompasses various layers of security designed to secure the data including tamper resistant enclosures, 256-bit encryption and an Industry based standard Trusted Platform Module (TPM) formed to ensure both security and the full chain of custody of data.

Amazon AWS  is based on a Red Hat Enterprise Linux (RHEL) variant and supports numerous Linux distributions and Windows Server 2003, 2008, and 2012 with the Xen hypervisor. Amazon’s cloud also supports Docker containers as mentioned above also with ten chief data centers around the globe, AWS is also an ideal choice for various multinational companies also small business enterprises.

Amazon Web Services Pricing

 Amazon Web Services Pricing is not as easy as it claims to be. They can argue that it is the cheapest service yet for customers making extensive use of all of those customizable services, Amazon can quickly nickel and dime anyone to a substantial price like any cloud platform vendor is going to argue that you can save money moving to the cloud.
The Amazon Cloud pricing is maintained in three ways:

 Amazon Cloud pricing

1. Pay-as-you-go: It allows you to simply become accustomed to changing business needs without over committing budgets and improving the responsiveness to any changes, by paying for services on need basis, the pay-as-you-go model adapts to the business depending on the needs and not on the predictions.

2. Pay less by suing more: A team of developers can get volume based discounts and observe the important savings as the usage increases. The pricing is tiered for products like S3 and EC2, paying less for more GBs used. The data transfer here is free of charge, AWS’ storage services portfolio provides factors to help lower pricing based on how frequently one access data and the needful performance to retrieve it. In this plan, one can optimize the savings by choosing the right combination of storage solution while reducing the cost. For instance :

S3 use for – UP to 50TB Storage : charges 0.023 GB/month
S3 use for –  51-100TB Storage   : charges 0.022 GB/month
S3 use for –  500 TB +Storage   : charges 0.021 GB/mont
Standard – Infrequent Access Storage has a minimum billable object size of 128KB
Standard – Infrequent Access Storage is charged for a minimum storage duration of 30 days

  1. Save when you reserve: Here invest in reserved capacity, possible to save upto 75% over equivalent on-demand capacity. Here the larger the upfront payment, the greater the discount. One can pay all up-front and receive the largest discount. With this plan, the organization can also minimize risk and comply with policies that require longer-term commitments. It also offers the flexibility to change families, OS types, and tenancies by benefitting from RI pricing while the use of  Convertible RIs.

EC2 RIs (reserved instances )  give a discounted hourly rate with an elective capacity reservation for EC2 instances. AWS Billing by design applies to the  RI’s discounted rate when attributes of EC2 instance usage match attributes of an active RI. It consists of ‘Standard RIs’, ‘Convertible RIs’ and ‘Scheduled RIs’.

Here is the difference between Standard RIs and Scheduled RIs.

Characteristic Standard Convertible
Terms (avg. discount off On-Demand) 1yr (40%), 3yr (60%) 3yr (45%)
Change Availability Zone, instance size (for Linux OS), networking type Yes (Using Modify Reserved Instances API and console) Yes (Using Exchange ReservedI nstances API and console)
Change instance families, operating system, tenancy, and payment option Yes
Sellable on the Reserved Instance Marketplace Yes (After linking account with a US bank account) Yet to Launch

How to Install AWS

AWS has such vast services with humongous options to chose from that it can be hard to determine what you’ll know and how much you’ll end up paying for it. AWS has been also assertively lowering its prices in the apparently unending price war against key competitors such as Google Cloud Platform and Microsoft Azure. As long as one keep an observational eye on what charges they are incurring on a regular basis they should be doing well.

Amazon Web Services

Installing AWS Command Line Interface:
The first step is to signup for an AWS account and set up the CLI environment.
1. Open https://aws.amazon.com/, and then choose to Create an AWS Account.
2. Follow the online instructions.
The sign-up procedure also  involves receiving a phone call and entering a PIN
Once the above two steps are done, the AWS sends a confirmation email on the registered email Id.

Requirements for Installation :
-Python 2 version 2.6.5+ or Python 3 version 3.3+
-Windows, Linux, macOS, or Unix
The primary distribution method for the AWS CLI on Linux, Windows, and macOS is ‘pip’ :  a package manager for Python which provides an easy way to install, upgrade, and remove Python packages and their dependencies.

In case you already have pip and a supported version of Python, follow the command :

$ pip install –upgrade –user awscli

upgrade: used to inform pipe to upgrade any requirements
the user: informs pip to install the program to a subdirectory of the user directory to avoid modifying libraries.

Once you install the AWS CLI add the path to the executable file to the  PATH variable.
Verify the AWS CLI installed correctly by running  ‘aws –version’ with the following code:

$ aws –versionaws-cli/1.11.44 Python/3.4.3 Linux/4.4.0-59-generic botocore/1.5.7

To update to the latest version of the AWS CLI : $ pip install –upgrade –user awscli

AWS offers building blocks that anybody can use rapidly to support virtually any workload in an organization. With AWS it is evident to find a complete set of highly available services that are planned to work mutually and build sophisticated scalable applications. Despite the price, is the most valuable and trusty solution of the cloud crowd and used for Delivering and deploying machines and environments to clients in a very quick way. Such services help organizations move faster, lower IT costs, and scale. AWS Cloud Computing is entrusted by the largest enterprises and the hottest startups to power a wide variety of workloads including the web and mobile applications, game development, data processing and warehousing, storage, archive, and many others.

So this was all about the Amazon Web services and how to install AWS, for any query you can leave a comment below we will reply you at the earliest.

 

Types of Cloud Computing

By now you must have heard about the cloud, and also you have likely heard about benefits of using the cloud computing for your enterprise and business, so, for now, we are going to detail about types of cloud computing. But still, most of the people from outside the world of IT may not know about the multiple types of cloud computing and their advantages and disadvantages. So here we are going to make you understand about the different types of cloud computing. Cloud computing moreover if asked in simple terms then it can be defined in one of the two ways such as  Cloud deployment model based on the cloud location or on the services that are offered by the cloud. Each of the types of deployment method and cloud services provides the user with different levels of management, control, and flexibility. So understanding differences between both of these will help you to decide that what set of the model as well as service is best for you.

types of cloud computing

Cloud Computing Types and Services

So here we are going to classify cloud on a different basis.

Classification on the basis of cloud location.

Based on the location cloud can be classified as the private, public and hybrid.

  1. Public Cloud: At first talking about the public cloud, here the computing infrastructure is hosted by cloud vendor at the vendor locator itself. The customer didn’t have any control and visibility over where the cloud infrastructure is hosted in which the service provider makes the resources, like applications and storage, that are available to the general public over the web/internet. Public cloud services can be free or it can be offered on a pay per usage model. Its name is the public cloud as the computing infrastructure is shared between the organizations. Below are the characteristics of the public cloud.
  • Easy to Use: Some of the developers favors the usage of public cloud due to fact its ease of access. Also the public cloud operates at the pretty fast speed, that is also alluring to some of the enterprises.
  • Cost effective: As the public cloud uses pay per use model so it is very cost effective way, and users can easily make use of this model.
  • Operated by the third party: The public cloud is operated by the third party and is not specific to a single person, business or any enterprise also it is constructed with the shared resources.
  • Flexible: Public clouds are flexible enough as it allows its users to easily add or even drop the capacity, and also are typically accessible from any of the internet connected device.
  • Can be quite unreliable: Public cloud outages recently made headlines in the recent weeks, leading to the headaches for its users.
  • Less secure: Public cloud offers often the lower level of security and are more susceptible to hacks.

Types of cloud computing with example:

  • Amazon Elastic Compute Cloud (EC2)
  • IBM’s Blue Cloud
  • Google AppEngine
  • Sun Cloud
  • Windows Azure Services Platform

2. Private Cloud: Here in private cloud, the computing infrastructure is implemented within the corporate firewall, all under control of the IT department mainly. As the name suggests it is not shared with other organizations. But some of the experts consider and believe that private cloud is not the real example of the cloud computing. In respect to public cloud, private cloud are much more secure and expensive as well. Below are some of the main features of private cloud.

  • Organization-specific: Private cloud are developed and offers services specifically to one organization or enterprise, as like public cloud they are not shared among many users.
  • More control and reliability: The infrastructure and services of private cloud are maintained onsite or in a privately hosted environment such as the third-party data center. This provides and the enterprise/ organization all over control over access.
  • Customizable: IT can easily customize storage as well as networking components so that the cloud can be a perfect fit for the particular organization and its requirements.
  • Costly: When compared to the public cloud, private cloud is much more costly due to its increased management responsibilities and private service that it offers.
  • Required IT expertise: Some of the organizations may not have infrastructure so that to completely build out as well manage a custom private cloud within their own IT department. So in these type of cases, a managed private cloud may be a viable option for everyone.

Private cloud is also categorized in two types

  • On Premise private clouds
  • Externally Hosted private clouds

Externally hosted private clouds are usually used by one organization but they are hosted by some other third party specializing in the cloud infrastructure. Externally hosted private clouds are also much cheaper than the on- premise private cloud.

3.  Hybrid Cloud: When both the clouds public as well as private are used together then t is referred as the hybrid cloud. Such as, organizations may host the critical applications on the private clouds and applications that are with relatively less security concerns on the public cloud. Below are some of the main features of the hybrid cloud.

  • Flexible and scalable: As the name suggests the hybrid, a combination of bith private as well public cloud, so here companies have the ability to mix and match for the ideal balance of the cost and security.
  • Cost effective: As hybrid cloud offer both types of the facility so businesses can take this advantage of the cost effectiveness of the public cloud computing while enjoying security feature of the private cloud.
  • Widely popular: Due to its features many of the enterprises are adopting hybrid cloud.

So, ultimately it can be said that it looks to be a promising solution for the future.

4.  Community Cloud: It includes sharing of the computing infrastructure in between organizations of the same community. For example all the Government organizations that are within the state of Washington can easily share computing infrastructure on the cloud so that to manage the data related to the citizens residing in Washington.

This was the classification that was based on the location of cloud, further cloud can be classified as the based on the services it offers.  So according to the services, it offers below are the 5 types of services with their advantages they bring to business and what is required for them to implement the each service.

Cloud Computing Services

Cloud Computing Services

  1. SaaS (Software as a Service)

The capability which is provided here to the customer is that to use the provider’s applications that are running on a cloud infrastructure. All the applications are accessible from the various client devices such as through either thin client interface like the web browser (for example web based email) or a program interface. The customer doesn’t manage or control the s underlying cloud infrastructure including network servers, storage, operating systems or even the individual application capabilities, with the possible exception of the limited user-specific application configuration settings.

Advantages of Using Saas for a business

Minimized IT support costs

Minimized IT capital expenditure

What is required to use SaaS?

Connection to the service provider via a secure internet connection such as VPN, Web SSL, MPLS, etc. The Certain type of SaaS solutions are mostly delivered via a program interface that runs on the customer equipment.

2.  PaaS (Platform as a Service)

The capability provided in the PaaS to the customers is to deploy onto the cloud infrastructure customer created or acquired applications that are created using the programming languages, services, libraries and the tools that are supported b the provider. The customer doesn’t manage or control underlying cloud infrastructure that includes operating systems, or any storage but has the control over deployed applications/data and also possibly configuration settings for application-hosting environment.

Advantages of using PaaS

Pass helps business and allows them to focus on the applications and not the underlying hardware, OS, middleware. The flexibility of PaaS enhances the agile software development methodologies. Here with PaaS you get reduced cost and complexity since the customer will not be able to maintain the underlying OS/middleware.

Requirements to use PaaS

The requirements for the PaaS are the connection to the service provider through a secure internet connection (Web SSL, MPLS, VPN etc).

3.  IaaS (Infrastructure as a Service)

Here with IaaS, the capability that are provided to the customer are to provision p[rocessing, networks, storage and many other fundamentals computing resources where the customer is able to deploy and also run the arbitrary software that includes operating systems and the applications. The customer here maintains and also has the control over the operating systems, deployed applications/data and the local storage.

Advantages of using IaaS

The advantages of using the IaaS are listed as below:

  • No large physical hardware expenditures is required
  • Alleviates the customer of complex capacity planning activities
  • Much more flexibility
  • The customer has all control over the OS/application installation, configuration as well as management.
  • Pay per use model
  • Scalable
  • Easy add-on/utilization of the other cloud provider offerings

Requirements of using IaaS

The requirements to use the IaaS are connection to the service provider via a secure internet connection (VPN, SSL, MPLS etc.)

4.  DRaaS (Disaster Recovery as a Service)

Here in DRaaS customers get the opportunity of replication and hosting of the customer’s server infrastructure to the geographically separate data center. Upon the customer declared failover event customer’s server infrastructure that will begin operating out of geographically separate datacenters in the minimal time frame and also at the same time ensuring continued business operations.

Advantages of using DRaaS

Minimum business operations downtime in event of the natural or man made the disaster. Each and every if there is an impact on the business then this only result in lost revenue. Most of the traditional methods can help to protect data and create the backup but at the time of disaster, there may be no functioning server infrastructure that is available on which the backups can be easily restored. Ith DRaaS this problem can be solved. This also eliminates the cost that is associated with that to maintaining and establishing the traditional private DR facility.

Requirements for using DRaaS.

The requirements that one needs to have for using DRaaS are the connection to the service provider via a secure internet connection (VPN, Web SSL, MPLS etc) also the compatible production virtual server infrastructure.

5.  BaaS (Backup as a Service)

Backup as service provides its customers to backup the data that actually resides in customers computing environment to the Metroplex’s secure remote BaaS environment. All the backup operations occur within the secure connection between remote Baas environment and data source. The customer has the overall control to perform or monitor backup/restore the operations through the self-service portal.

Advantages of using BaaS

Ease of management

Scalable backup capacity

Scalable backup retention length

No Offsite tape storage service costs

Requirements to use BaaS

The things that re required for BaaS are the connection to the service provider via a secure internet connection (VPN, Web SSL, MPLS etc). Both BPaaS and DaaS are the two of the other cloud services and are not regarded as the main one. So here we complete with the classification of cloud computing on the basis of the location of the cloud as well as services that are offered by the cloud. Once you have understood the importances of different types of cloud computing based on the location and service then the most important step is to choose the right type of the cloud and service as per your requirements.

Cloud Computing Services

Cloud computing is the technology of the future and it is truly facilitating the way a company’s mobile workforce is conducting the business. Cloud solutions basically allow the businesses to grow to forgo all the upfront costs of building the local data center by outsourcing all important services that are needed to run, maintain and grow the change to your business cloud-based infrastructure.

There are so many advantages of cloud computing such as  lower upfront costs and reduces infrastructure costs, only pay for what you exactly mak use of, overall environmental benefits, everything managed under SLAs and much more that’s the reason most of the companies are making use of cloud computing so be one of them you too. We hope that you are finding the above information useful for you to understand the types of cloud computing public private hybrid technologies.

Advantages & Benefits of Cloud Computing

What is the cloud? Where is this cloud? And many more such types of questions you must have in your mind and will be asking to yourself. You are not aware of this fact but let me tell you that “cloud computing is everywhere”. So before moving on to the advantages of cloud computing let’s first understand what is cloud computing all about then only you all will be able to understand all its benefits and advantages.

In simple terms, cloud computing is used to store as well as access the data and programs over the internet instead of your hard drive. Cloud can be referred as just a metaphor for the internet. Also, the cloud computing is not only about as your hard drive. When you store some information or data or run the programs from the hard drive, this is called the local storage and computing. Everything that you require is close to you, which means that it gets easier for you to access the data. If you think that cloud is all about Network attached storage hardware or server in the residence then let me tell you this is not true. To consider it as the “cloud computing” you have to access the data and your programs over the internet or otherwise, that data should be synced with some other information over the web. So here we are going to discuss all the benefits of cloud computing.

 benefits of cloud computing

So nowadays cloud computing is not a new trend or technology, as the adoption of the cloud computing is increasing at a very fast speed and can be considered by the companies as one of the appropriate and promising options in recent years that not only decreases the costs bit also to position the offerings and services competitively. Cloud computing have transformed all its way the business is conducted, service is delivered and the technology consumed.

Cloud computing offers its customers many economic advantages, agility, speed, flexibility, scalability, accessibility and innovation. Most of the companies are looking towards cloud computing as one of the strategic move which impacts their business and rather than just being a cost effective approach. Industries or organizations are getting more responsive than they were earlier by adopting the digital business strategy, IT industry is also witnessing nowadays a growth in the adoption of cloud computing services that indicates the shift from IT services to the cloud-based services. There are some of the factors that one should look for while adopting the cloud computing services/ technology.

Factors to consider while adopting Cloud computing

Cloud computing should be the strategic move by the organizations while adopting that consists of the careful planning, execution and the management taking into consideration the long-term goal to get the desired results as it is one of the major decision to be made by any organization. The adoption of cloud computing starts from the identifying right type of cloud provider from whom you will taking advantage of cloud computing services, transitioning the client servers / web server hosted systems to cloud and then at last implementing suitable type of automation/ third party tools to enable the the migration and also while giving all importance to the testing to ensure that data, applications or software that are migrated to or are hosted on the cloud work as the intended. Below 3 major points have been listed down that one should look for while adopting the cloud computing.

advantages of cloud computing

  • At first, the organizations should evaluate the suitability of the deployment models that are available such as public cloud, private cloud or hybrid cloud. And from all of these choose the best one that matches with your business goals.
  • Nest thing that organizations should go for is that the organizations should assess all the 3 main cloud service models that are SaaS, PaaS, and IaaS, which one is best for their business and as per the availability in the market.
  • Now the last one and most important also, cloud computing involves 5 most important characteristics as mentioned here- demand self-service, resource pooling, measured service, broad network access and rapid elasticity. So, the organizations who are planning to adopt cloud computing services should also take this point into consideration.

Now lets’ move on the some of the major benefits or advantages of cloud storage.

Cloud Computing Advantages

Below is the list of cloud computing benefits that one should look for before opting the technology.

Cost Savings:

If you are worried the cost that will be incurred while making a switch and adopting the cloud computing services then let me ensure you that you are not all alone. As 20% of the organizations are worried about the costs that will be there in implementing the cloud-based server as the initial cost. But as you are concerned about the initial cost of cloud computing so you must also consider the advantages and benefits of using cloud computing.

As once you are on the cloud, then it will be so easier for you to access the company’s data which will save your time as well as money in the project start-ups. Also for all those who are worried that they might have to pay for the features that they don’t even need then there is no need to worry as there are most of the cloud computing services that are based on pay-as-you-go. This means that if you don’t benefit of what is offered to you by cloud then you don’t need to spend money on that. Pay-as-you-go system is also applied to data storage space that is needed to service your stakeholders and clients that mean means that you will get the space as required by you.

Security:

One of the major that holds the organizations from taking the cloud service is security. The major concern is that all the files, programs as well as other data is not secured on the site then how one can know that they all are being protected. But you might not know that the cloud host’s full time is just to carefully monitor the security and accordingly it is one of the most efficient methods than the conventional in-house system where an organization divides all its efforts between the myriad of IT concerns, with security as one of them. While most of the organizations don’t like to consider the possibility of the internal data theft but this is the bitter truth which is the staggeringly high percentage of the data thefts occurs internally and which is penetrated by the employees. So in this case, it is intelligence to keep the sensitive information off-site.

There is a claim from RapidScale that 94 percent of businesses saw improvement in the security when switched to the cloud and also 91 percent also said that cloud makes it much easier to meet all the government compliance requirements. The key to this cloud computing security is the encryption of the information or data which is being transmitted over the networks and stored in the databases. As you might aware that by means of encryption data is less accessible by the hackers and is less prone to get hacked. In cloud as an added security measure, with most of the cloud-based services, many different security settings can also be set and based on the user.

Flexibility:

Cloud computing provides as much flexibility with its services that you can’t even think of. So if your current IT solutions are for actually forcing you to commit and provide so much of your attention to the computer as well as data storage issues then you will not be able to concentrate and reach to the business goal that is set by you and the customers will also not satisfied by you. On the other hand, by relying upon some other outside organization to take care of all the IT hosting and infrastructure, here you have to devote more time towards the aspects of your business which directly affects your bottom line.

So from here, one can infer that cloud offers organizations or businesses much more flexibility overall comparing to the hosting on a local server. Also if you require extra bandwidth, then cloud-based service can fulfill that demand instantly rather than undergoing expensive as well as a much complex update to your IT infrastructure.  This improved flexibility and freedom provided to you by the cloud can increase your overall efficiency.

Mobility: Cloud computing also provides this facility to mobile access to corporate data via your smartphones and any other device, as considering the fact that over 2.6 of the billion smartphones are actually being used overall in the world, and it is one of a great way to ensure that no one should leave out from the loop. The staff of the corporate with that busy schedule or all those who live a long way away from the offices, all those can take advantage of this feature to always remain up to date with their coworkers and clients. With the cloud, you can also provide the accessible information to the sales staff who travel to [places, remote employees, freelance employees for the much better work life balance.  So there is no surprise that organizations for their employee satisfaction are up to 24 percent much more likely to expand the cloud usage.

Insight: As we are moving ahead into the digital era it is becoming much more clear that “Knowledge is the power” has actually taken a modern form and can be now said as “Data is money”.As hidden in the millions of bits of the data that is actually surrounding your customer transactions as well as business processes are such nuggets of invaluable, and actionable information which is just waiting to be get identified and acted upon.

Many of the cloud-based storage solutions also offer the integrated cloud analytics for the bird’s eye view of your own data.  As when your data will be stored in the cloud, you can easily implement all the tracking mechanisms and also to build the customized reports to analyze the information organization-wide. From all those insights collectively one can increase the efficiency and build the action plans to meet all the organizational goals.

Increased Collaboration: Thinking upon that which organization can take advantage from this then note down that if your company is having more than the two employees then you must make collaboration your top and main priority. As there is no use if the team can’t work as being in a team. Cloud computing makes collaboration a much simpler process. All the team members in the company can easily now easily view and share the information and securely across the cloud-based platform. Some of the cloud-based services also provide the collaborative social spaces to connect to the employees across the organization. , therefore increasing the engagement as well as interest. Collaboration is also possible without the cloud computing but it will not be that effective.

Quality Control: In the cloud computing you will get all the documents and data are stored in the one place and even in the single format. Also, everyone will be accessing the same information, so you can maintain the consistency in the data, can avoid human error and will also have all the clear records of any revisions done and updates.  And conversely, managing the information in the silos can also lead to the employees to save the different versions of the documents that can also lead to the confusion and diluted data.

Disaster Recovery: This is one of the factors that leads to the success of the business in under control. , But unfortunately no matter how your organization is being controlled when it comes to the own processes, there will always be the things which are out of the control and if we see in today’s market also even the small amount of unproductive downtime can have the negative effect. Downtime can lead to the lost productivity revenue and brand reputation. But also there might not be any of the ways to actually prevent or anticipate disasters which could potentially harm the organization, and there is something which you can do to help the speed up your recovery process.

cloud computing benefits

Loss Prevention: If the organization is not investing into the cloud computing solution then all of your data which is very much valuable in inseparably tied to office computers it actually resides in. This may not seem like the problem but in reality, if we see that if the local hardware experience some kind of problem then you can lose your data for permanent basis. This is the most common problem that you can realize, there are so many reasons by which computers can actually malfunction such as the viral infections, age-related hardware deterioration or a simple user error, anything can be a reason. Or despite all these, they can be stolen or misplaced. So if you are not on the cloud then you might be at risk of losing your data/ information that has been stored by you locally. Whereas with the cloud-based servers, all the information that you have uploaded to the cloud remains the safe and easily accessible too from any system just with an internet connection.

Automatic Software updates: Now for all of those who have to wait for the system updated to get installed and then they can start their work which is very much irritating. You might not be aware but all the cloud-based applications automatically refresh and also update themselves instead of giving burden on to the IT department to perform manual updates which are also a time taking the task. This saves your valuable time and money that you have to spend on outside the IT consultation.

Competitive Edge: While cloud computing is becoming so popular but still there are many people who usually prefer to keep each and everything local. This is their choice but there is a disadvantage of this as they will be competing to all those who have the benefit of cloud computing in their business. And if you will implement the cloud-based solution all before your competitors then you will further along the learning curve by the time your competitors catch up.

Sustainability: Real sustainability requires the solutions of all the problems that actually deals with the wastefulness at every level of the business.  Hosting on to the cloud is much more environment-friendly and can also result in the carbon footprint. But here in cloud computing, it supports the environmental proactivity.  That are powering the virtual services rather than the physical products and hardware and cutting down the paper waste, improving the energy efficiency and  minimizing the computer related emissions

So all these were the advantages of cloud computing. If you have any query regarding the post or anything else you can leave a comment below, we will reply to you at the earliest.
