FAULT TOLERANCE IN GRID COMPUTING USING WADE

Abstract

Grid computing is a coordinated resource sharing and solving the problems in organizations which are dynamic and virtual in nature. Apart from the dynamic nature of grids which means that resources may enter and leave the grid at any time, in many cases outside of the applications, control grid resources are also heterogeneous in nature. Many grid applications will be running in environments where interaction faults are more commonly occur between diverse grid nodes. As resources may also be used outside of organizational boundaries, it becomes iteratively difficult to guarantee that a resource being used is not malicious one. Because of the diverse faults and failure conditions developing, deploying, and executing long running applications over the grid remains a challenge. Hence fault tolerance is an primary factor for grid computing. The prototype system is designed using agents to provide service replication, reactivation and avoids the single point of failure. The agents and the workflows are provided by a common software platform called WADE.
