Developing an End-to-End Scientific Workflow:

Grid-based simulation usually involves sequences of activities such as resource discovery, job submission, file transfer, analysis and simulation, and data harvesting. We can use service-oriented workflow to automate task coordination without direct human control, where each task and legacy scientific code can be presented as a Web service and thereby simplifying workflow development and maintenance. Because each service is described using Web Service Description Language, workflow manager works only with the WSDL interface rather than specific implementations.
