The impact of Cloud Computing is so high that, Forbes in its Cloud Computing Forecasts projected it will witness an increase to $162B in 2020 from $67B in 2015attaining a compound annual growth rate (CAGR) of 19%.

What is Cloud Computing?

It was not very long ago when people had to maintain a pile of physical documents which if lost or misplaced could cost a great deal. Cloud Computing has transformed how the internet was used completely-enabling storing data in a centralized location which can be accessed from computer and mobile device anytime anywhere. Whether it is pictures, important data, now with the access of cloud, sharing files has never been so easy. To sum up, Cloud literally acts as a virtual drive or maybe more than that.

Cloud Computing Service Models

Cloud services are based and categorized on three service models, namely- Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).

IaaS in cloud computing: The first layer of Cloud, IaaS or Infrastructure as a Service involves delivering cloud computing infrastructure where third party providers such as Amazon Web Services, Microsoft Azure or Google, hosts virtualized computing resources over the Internet. Here customers can pay as per their use which enormously eliminates the expenditure goes on deploying in-house hardware and software.

PaaS in cloud computing: Platform as a service (PaaS)- the second cloud layer is a cloud computing model that enables delivering applications over the internet where a developer can easily create, run, test and manage the applications over cloud. In a PaaS model, a cloud provider can accommodate the software and hardware on its own infrastructure without having to worry about consuming IT infrastructure activities such as provisioning servers, backup, and storage. Few PaaS examples are Microsoft Azure, Google Apps Engine and AWS Elastic Beanstalk.

SaaS in cloud computing: SaaS or Software as a service is the third layer, which is also popularly known as ‘on-demand software’, it is a software distribution model where applications can be hosted centrally on the cloud server and can be accessed directly without downloading or installing. Customer Relationship Management, Human Resource Solutions, Billing and Invoice System are some of the examples of SaaS applications.

Deployment Models in Cloud Computing

Private Cloud: Provides its services exclusively to a single enterprise or institution. In Private Cloud model the cloud infrastructure can be tracked only by the cloud provider or the user.

Public Cloud: In the Public Cloud model, the services and infrastructure remain open to use for the general public. While the users have no control over the location of the infrastructure, they can access the services over a public network such as the internet.

Hybrid Cloud: This Cloud model is basically the amalgamation of both Public Cloud and Private Cloud infrastructure where the particular enterprise or institution using it can benefit in the aspect of attaining scalability, flexibility, and security.
