A collaborative services grid portal architecture based on OGSA

This paper focuses on solving problems of the existing Grid Portal scalability, portability and adaptability. To overcome the weakness of collaborative services ability in different grid portal, a new grid portal architecture based on CSGPA (Collaborative Services Grid Portal Architecture), is proposed. The CSGPA is built on the basic of OGSA (Open Grid Services Architecture). It divides the grid service into Portlet grid service and application grid service, and separates the display logic from the application logic of grid portal. In the paper, the application system architecture of grid portal based on CSGPA is presented according to network topology and application distribution of grid system. In comparison with the current mainstream grid portal architecture, the results show that CSGPA has great advantage in efficiency, deployment costs, scalability and reusability etc. It is a better grid portal architecture.
