Cloud computing

Cloud computing is a general term for anything that involves delivering hosted services over the Internet. These services are broadly divided into three categories: Infrastructure-as-a-Service ( [|IaaS] ), Platform-as-a-Service ( [|PaaS)]  and Software-as-a-Service ( [|SaaS] ). The name cloud computing was inspired by the cloud symbol that's often used to represent the Internet in [|flowchart] s and diagrams.



 Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.

 A simple example of cloud computing is Yahoo email, Gmail, or Hotmail etc. You dont need a software or a server to use them. All a consumer would need is just an internet connection and you can start sending emails. The server and email management software is all on the cloud ( internet) and is totally managed by the cloud service provider Yahoo, Google etc. The consumer gets to use the software alone and enjoy the benefits. The analogy is, '  //**If you need milk , would you buy a cow ?'** All the users or consumers need is to get the benefits of using the software or hardware of the computer like sending emails etc. Just to get this benefit (milk) why should a consumer buy a (cow) software /hardware ? //  media type="youtube" key="ae_DKNwK_ms" height="334" width="594" align="center"
