'''Open Grid Services Architecture''' ('''OGSA''') psnacetdescribes a [[service-oriented architecture]] for a [[grid computing]] environment for business and scientific use.

It was developed within the [[Open Grid Forum]], which was called the Global Grid Forum (GGF) at the time, around 2002 to 2006.

==Description==

OGSA is a distributed interaction and computing architecture based around services, assuring interoperability on heterogeneous systems so that different types of resources can communicate and share information. OGSA is based on several other [[Web service]] technologies, such as the [[Web Services Description Language]] (WSDL) and the [[Simple Object Access Protocol]] (SOAP), but it aims to be largely independent of transport-level handling of data.

OGSA has been described as a refinement of a Web services architecture, specifically designed to support grid requirements.<ref>[http://www.nesc.ac.uk/teams/OGSAanalysisDennisGannon.pdf An Analysis of The Open Grid Services Architecture]{{Dead link|date=August 2025 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>

The concept of OGSA is derived from work presented in the 2002 [[Globus Alliance]] paper "The Physiology of the Grid" by [[Ian Foster (computer scientist)|Ian Foster]], [[Carl Kesselman]], Jeffrey M. Nick, and Steven Tuecke.<ref>{{Cite web |title= The Physiology of the Grid: An Open Grid Services Architecture for Distributed Systems Integration |author= [[Ian Foster (computer scientist)|Ian Foster]], [[Carl Kesselman]], Jeffrey M.
