Grid computing can dramatically lower the cost fo computing,extend the availability of computing resources, and deliver heigher productivity and quality.
The basic idea of grid computing is the notion of computing as a utility, analogous to the electric power grid or the telephone network.As a client of the grid, you do not care where your data is or where your computation is done. you want to have your computation done and to have your information delivered to you when you want it. From the server side, grid is about virtualization and provisioning. you pool all your resources together and provision these resources dynamically based on the needs of your business, thus achieving better resource utilization at the same time.
