Grid Service Grid Service Grid Service Grid Service Grid Resources Computer Storage Device ... OGSA(Open Grid Services Architecture) Overview • Open standard of Grid Computing • Service Oriented Model/Architecture • Question: How to manage so many grid resources or grid services? • Answer: MetaServices
Grid Service Grid Service Grid Service Grid Service Raw Grid Resources Computer Storage Device ... MetaServices Concept • MetaService: the Grid Service which is used to manage other grid services(resources), MetaService Resource Service Grid Applications High Level Grid Middleware MetaService MetaService MetaService Managed Grid Resources
