A Review: Grid Computing

A grid is a hardware and software infrastructure that allows service oriented, flexible, and seamless sharing of diverse network of resources. A grid is to compute data intensive tasks and provides faster throughput and scalability at lower costs. The aim of grid computing is to provide an affordable approach to large-scale computing problems. The geographically isolated computational resources combined within a grid viewed as a virtual supercomputer. This paper tells about the various types of grid, Grid Architecture, OGSA, Fault Tolerance, Load Balancing, and various challenges in grid computing.
