GEONGrid portal: design and implementations

We have developed the GEONGrid system for coordinating and managing naturally distributed computing, data, and cluster resources on the cyberinfrastructure. Recently, since the use of Grid technology is still very complex for researchers and scientists, the area of Grid Portals has made excellent progress. The Grid portal system is an emerging open Grid computing environment that promises to provide users with uniform seamless access to remote computing and data resources by providing an easy to use interface to cover over the complexity of more sophisticated Grid technologies. In this paper, we present our initial efforts in the design and implementation of service components in the GEONGrid portal. These service components may be implemented as Web services that follow the conventions of service‐oriented architecture design. In this approach, service components are self‐contained, have a well‐defined programming interface defined in WSDL, and communicate using SOAP messaging. In building a GEONGrid portal, we also use a component‐based user interface design. Portlets provide the desired component model for user interfaces in the same way as Web services. Using this approach, which allows Grid portals to be built out of reusable components, has the obvious advantages of reusability and modularity. Copyright © 2007 John Wiley & Sons, Ltd.
