In today's world of technological advancements, cloud computing is all the rage.

There are numerous definitions available in the market that describes this newly coined technology. Some research firms and cloud hosting providers define it as an updated version of utility computing, whereas for some it refers to the virtual servers available over the Internet.

In reality cloud platform comprises of any subscription based or pay per usage service that extends IT capabilities over the Internet within real time period.

To elucidate further, Cloud computing comprises of the following three deployment models:

SaaS: Also known as Software as a service refers to an on -demand software. It is a software delivery method, wherein the access to the software and the functions is provided remotely through web. In this type of cloud computing, a single application is provided through the browser to numerous customers using multi-tenancy architecture.

SaaS has multiple benefits both for users and service providers. It ensures no upfront costs in buying servers, hardware or software licenses and ensures maintenance of a single app at low cost. Primarily SaaS applications are designed for the end users and are delivered over the Internet.

PaaS : Platform as a service helps to design own applications that operate on the service providers infrastructure and are delivered to the cloud users through the Internet. In PaaS, a service provider rents hardware, storage and network capacity, operating systems over the Internet.

It can be comprehended as an extension of Saas, that comprises of various tools and services that are formulated to make the coding and deployment of applications quick and effective.

IaaS: Infrastructure as a service refers to the delivery of cloud computing infrastructure that consists of servers, storage, operating systems, bandwidth, load balancers and network. With IaaS the access to the various computing resources is facilitated in a virtualized environment over the Internet. It provides the benefits of cost effective and scalable IT solutions that ensure a reduction in the expenditure and the complexity involved in managing the hardware provided by the cloud provider.

Hence, one can improve the overall operational efficiency and business agility by leveraging the benefits of these three cloud-based models and stay ahead in competition.
