Grid computing shares the distributed computing resources and unites the virtual organization spread in the different geographic situations to deal with large scale and data intensive computation together. In order to make grid application program use the variety of resources effectively and conveniently some reasonable mechanisms must be adopted to monitor and discover these resources to provide stable, reliable and high-efficiency application environment. This paper main to explore the problem of how to solve the information service application in grid computing environment, construct simulation platform and simulate information service implement procedure by adopting the service-oriented architecture.
