DESCRIPTION

This presentation explores Open Grid Services Architecture (OGSA) in the context of UK e-Science, detailing how it facilitates resource management, application availability, and business integration. Simon Laws from IBM UK Hursley Laboratory discusses the distinction between standards and variety within service specifications (WSDL, BPEL4WS), and emphasizes the importance of high-level patterns, registries, and service domains. The roadmap for OGSA's future adoption highlights the integration of resources, technologies, and organizational flexibility necessary for achieving continuous accessibility and scalability in e-Science initiatives.

  1. OGSA: The Platform for UK e-Science Simon Laws IBM UK Hursley Laboratory Hursley Services and Technology

  2. OGSA In UK eScience • Unification • What is a service? • There is a line between specs that must be the standards (WSDL?) and specs where there is bound to be variety (BPEL4WS / WS-C) • Patterns • High level things (Registries / Service Domains) • Lower level things (State vs Context / Big “F” and little “f” factories / Policy and agreement) • Models (Resource / Agreement) • Adoption • What is the roadmap (Non OGSA / OGSA today / OGSA tomorrow)
