A Workflow Engine-Driven SOA-Based Cooperative Computing Paradigm in Grid Environments

Grid has been proposed to be a promising service-oriented platform for increasingly complex cooperative computing. The platforms of service-oriented Grids are often web-based where participants collaborate to achieve a common goal by sharing scarce Web-Based Computational/Computing Resources (WBCR). To effectively share the WBCR is a challenging problem in boundary-spanning grid environments, particularly when these resources are subject to both static and dynamic usage. To set up a certificate-based usage policy in this paper, we firstly explore a workflow engine-driven SOA-based resource access control mechanism. Then, aiming at setting up a cooperative computing paradigm from the resource sharing perspective, a infrastructure derived from a specific project of SOA&EDSCCE (SOA-Based&Engine-Driven Structured Cooperative Computing Environment) is proposed for promoting its cooperative computing in grid environments based on the control disciplines and the WBCR usage policy. The main contributions of this paper are twofold: 1) a workflow engine-driven SOA-based WBCR sharing mechanism is presented according to the certificate-based usage policy; and 2) a specific infrastructure of cooperative computing is put forward for the collaboration based on the WBCR sharing mechanism.
