MetaGrid: a scalable framework for wide-area service deployment and management

Presents an architecture called the MetaGrid based on Grid computing concepts for resource provisioning for wide-area network-enabled applications. Resource provisioning for wide-area applications can involve coordinated allocation of computing and communication resources. A Grid computing system provides a virtual framework that facilitates controlled resource sharing among different institutions. The MetaGrid extends the Grid computing systems in two major ways: (a) introduces a notion of SubGrid that provides a coarse-grained resource allocation class and (b) introduces a framework for interconnecting Grids by facilitating peering, trading, and brokering among the different Grids. The paper presents (a) the overall architecture of the MetaGrid with a description of the different functional components, (b) the resource allocation model that is introduced by the notion of SubGrids, and (c) strategies of interconnecting Grids.
