On-Demand Build a Virtual e-Science Workflow

A typical e-Science infrastructure contains GridSAM as Grid middleware, ActiveBPEL engine as workflow engine to build a workflow system. Grid Virtualization Service (GVS) is used to provide virtual machines as computing resources for the e-Science infrastructure. This paper emphasizes that a virtual e-Science infrastructure could be dynamically built and deployed by merging Grid Virtualization Service into the middleware level and the application level.
