Defining the Grid: A Roadmap for OGSA™ Standards
Hiro Kishimoto, Jem Treadwell · 2005
The Global Grid Forum (GGF) has embraced the Open Grid Services Architecture (OGSA) as the industry blueprint for standards-based grid computing. “Open” refers to the process used to develop standards that achieve interoperability. “Grid” is concerned with the integration, virtualization, and management of services and resources in a distributed, heterogeneous environment. It is “serviceoriented” because it delivers functionality as loosely coupled, interacting services aligned with industryaccepted Web service standards. The “architecture” defines the components, their organizations and interactions, and the design philosophy used. While much progress has been made with OGSA, there remains a lack of clarity concerning exactly what OGSA is, who defines it, what will be defined when, and who is contributing to its development. This informational document answers these questions by providing a snapshot of the evolving OGSA space and an explanation of the direction chosen by OGSA-WG and GGF.
