Cloud computing as a concept glues together several other, often independent, concepts in a complimentary way to open up new operating models and opportunities for the IT industry. Cloud Computing has evolved from, and extends into, several concepts that have been around for some time, such as SaaS, utility computing, grid computing, virtualization, realtime infrastructure, Web platforms, and SOA.

Gartner defines cloud computing as ‘a style of computing where massively scalable IT enabled capabilities are delivered as a service to external customers using Internet technologies’. Cloud computing basically has three layers, and using these layers mainly following services can be provided:

1. Infrastructure as a Service (IaaS)
* Physical infrastructure as a service - traditional data center services offered using utility pricing models.
* Virtual infrastructure as a service - virtual servers, logical disks, VLAN networks, and so on.
