I recently attended a seminar on Grid Computing. In this seminar, a common questions was asked by the participants. The question is, what is the main difference between Grid Computing and Cluster computing?. I would like to share a glimpse of these two.
If a number of computers are used together to solve a problem over internet is called cluster of computer. On the other hand, The cooperation among the computers to solve a problem is called as cluster of computing.
In Grid computing, though the same concept as cluster computer, however it is used for solving large problems. The main difference is that cluster is homogeneous, where as grid is heterogeneous. The cluster of cluster is also called as grid computing. Homogeneous in cluster means the computers are of same hardware and OS. The computers on the part of a grid run different OS and different hardware. Grid is normally distributed over Lan or Wan.
