It is a nice question. After reading your question I checked web and got answer.



(Refer link one given below)

Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.[1][2] Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them.[3]



The concept generally incorporates combinations of the following:



infrastructure as a service (IaaS)

platform as a service (PaaS)

software as a service (SaaS)

Other recent (ca. 2007鈥?9)[4][5] technologies that rely on the Internet to satisfy the computing needs of users. Cloud computing services often provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers.

The term cloud is used as a metaphor for the Internet, based on how the Internet is depicted in computer network diagrams and is an abstraction for the complex infrastructure it conceals.[6]



The first academic use of this term appears to be by Prof. Ramnath K. Chellappa (currently at Goizueta Business School, Emory University) who originally defined it as a computing paradigm where the boundaries of computing will be determined by economic rationale rather than technical limits.[7]
