Portlet-based Portal Design for Grid Systems

摘要

A Grid portal is a user's access point to Grid systems. A disadvantage existing in current Grid Portals is that they are usually designed for specific applications and difficult to adapt to new applications.Portlets are Java based web components, which makes a portal more flexible and can be easily reused. Grid systems have some common services, and these services are independent from each other somewhat. In this paper, we propose a portlet-based Grid portal architecture by encapsulating one or more Grid services to a portlet. This architecture enables a user to configure a Grid portal environment that suits him best and improves the reusability of the Grid portal. A portlet-based Grid portal prototype is implemented to evaluate the usefulness and effectiveness of the architecture.
