Towards an information infrastructure for the grid

In this paper we present our vision of an information infrastructure for grid computing, which is based on a service-oriented architecture. The infrastructure supports a virtualized view of the computing and data resources, is autonomic (driven by policies) in order to meet application goals for quality of service, and is compatible with the standards being developed in the technical community. We describe how we are implementing this vision in IBM today and how we expect the implementation to evolve in the future.
