Cloud computing compared to grid computing

Cloud computing is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet.

Grid computing is the application of several computers to a single problem at the same time. It is widely used where you need lot of computer resources to process resource intensive computational works such as web scrolling of Goolge search. it is also called distributed and large scale clustered computing.

It is a form of distributed computing whereby a "super and virtual computer" is composed of a cluster of networked, loosely coupled computers, acting in concert to perform very large tasks. This technology has been applied to computationally intensive scientific, mathematical, and academic problems through volunteer computing, and it is used in commercial enterprises for such diverse applications as drug discovery, economic forecasting, seismic analysis, and back-office data processing in support of e-commerce and Web services.
