Resource Grouping in Grid Environment Towards the Availability and Reliability of Computing Service

Abstract

Intermittent availability of grid resources results in delays or failures of application execution. Hence, the reliability of application execution declines. In order to achieve a reliable application execution, a consistent availability of computing service is required. This paper proposes a grid computing system that achieves a consistent availability in order to achieve a reliable application execution. In the proposed system, steady state availability is achieved for longer durations. Therefore, the system may be deployed to execute longduration applications. The availability and reliability of the proposed computing service is analyzed using a Markov model. Simulation results prove that the proposed system achieves better reliability and availability compared to the existing replicated application execution system proposed in grid environment.
