A new grid resource management mechanism with resource-aware policy administrator for SLA-constrained applications

Abstract

Due to the dynamic nature and an uncertainty of Grid computing, system behavior in terms of Quality of Service (QoS) depends crucially Oil the selection of appropriate subset of the available resources. Thus, a well-organized system architecture that provides high system availability using a scheduling mechanism for Grid applications is required. In this paper, we design an efficient architecture referred to as Resource-Aware Policy Administrator (RAPA) with Service Level Agreement (SLA) and real-time attributes in Grid resources and propose a new Grid resource management mechanism with an admission control scheme to make an optimal resource allocation policy for both satisfying QoS requirements in terms of deadline as well as profit and accepting more jobs. Also, we demonstrate detailed workings of the proposed schemes with the RAPA via a simulation study by using real-life parameters. The simulation results show that the proposed schemes have an effect oil accepting more jobs with satisfying the deadline of jobs and increasing service profits and Call guarantee high system availability in terms of system performance.
