Abstract
The grid has been proposed as 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 share the WBCR effectively
is a challenging problem in boundary-spanning grid environments, particularly when
these resources are subject to both static and dynamic usage. To set up the
certificate-based usage policy described in this paper, we first 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, an
infrastructure derived from a specific project of
