With the enormous increase in the demand for computing capacities, solutions with least investment have to found out. In this direction Grid technology is finding its way out of the academic incubator and entering into commercial environments. Here geographically distributed resources, such as storage devices, data sources, and supercomputers, are interconnected and exploited by users around the world as single, unified resource. This helps in use the idle time of these resources, which is otherwise lost. This article discusses briefly about grid computing and its benefits. Application of this technology is increasing and this article also looks at some of these applications.
