Fault-Tolerant Middleware for Grid Computing

The major challenge in Grid environment is fault tolerance. Faults ranging from machine crashes, media failures, operator errors and random data corruption results in loss of data, both temporarily and permanently. The paper proposes a solution for handling faults in grid environment. Fault-Tolerance using Adaptive Replication in Grid Computing (FTARG) is an adaptive replication middleware which addresses the fault tolerance of Grid based applications by providing data replication at different sites. FTARG is an Aneka based Grid middleware especially designed for high-performance Grid based applications. FTARG enables data synchronization between multiple heterogeneous databases located in the Grid by supporting a variety of synchronization modes. Experimental analysis proves that proposed FTARG handles faults in the Grid by improving the performance of data management for large scale complex grid based applications.
