Open Grid Services Infrastructure

The Open Grid Services Infrastructure (OGSI) was published by the Global Grid Forum (GGF) as a proposed recommendation in June 2003.[1] It was intended to provide an infrastructure layer for the Open Grid Services Architecture (OGSA). OGSI takes the statelessness issues (along with others) into account by essentially extending Web services to accommodate grid computing resources that are both transient and stateful.

Obsolescence

Web services groups started to integrate their own approaches to capturing state into the Web Services Resource Framework (WSRF). With the release of GT4, the open source tool kit is migrating back to a pure Web services implementation (rather than OGSI), via integration of the WSRF. [2]

"OGSI, which was the former set of extensions to Web services to provide stateful interactions -- I would say at this point is obsolete," Jay Unger said. "That was the model that was used in the Globus Toolkit 3.0, but it's been replaced by WSRF, WS-Security, and the broader set of Web services standards. But OGSA, which focuses on specific service definition in the areas of execution components, execution modeling, grid data components, and information virtualization, still has an important role to play in the evolution of standards and open source tool kits like Globus."[2]

Implementations
gollark: I think I may have made JackMacWindows dislike me, or at least my project.
gollark: PotatOS automatically turns it on if available for as yet unidentified porpoises.
gollark: Well, CraftOS-PC supports that as an option.
gollark: I think for a basic standard interface you could get away with something like `thing.run(function)` and it could return a handle which lets you stop it and stuff.
gollark: Yes, but then everyone ends up needing to ship one and it's annoying.
