  • Although cloud computing is an emerging field of computer science, the idea has been around for a few years. It's called cloud computing because the data and applications exist on a "cloud" of Web serversThe underlying concept of cloud computing dates back to the 1960s, when John McCarthy opined that "computation may someday be organized as a public utility". Cloud Computing came into commercial use around the turn of the 21st century.2007 saw increased activity, including Google, IBM.It was a hot topic by mid-2008 and numerous cloud computing events had been scheduled.
  • Users select a task or service (either starting an application or opening a document).User’s request goes to the system management, which finds the correct resources and then calls the system’s appropriate provisioning services.These services > Carve out the necessary resources in the cloud > Launch the appropriate web application > Opens the requested document.Web application is launchedSystem’s monitoring functions track the usage of the cloud so that resources are apportioned and attributed to the proper user(s).User is charged according to the amount of utilities and resources used.
