Cloud computing is really changing the way of computation. Many computer resources such as hardware and software are collected into the resource pool which can be assessed by the users via the internet through web browsers or light weight desktops or mobile devices. It is not a very new concept; it is related to grid computing paradigm, and utility computing as well as cluster computing. All these computing viz. Grid, cluster and utility computing, have actually contributed in the development of cloud computing.
