Grid middleware – principles of standartization

The subject of this article is an analysis of basic architectural principles of the grid middleware represented in the Open Grid Services Architecture (OGSA). At the present stage the grid middleware is developed by different teams, and availability of universally recognized architectural solutions establish favourable conditions for creation of an open, expandable software platform, in which typical functions to access distributed resources are implemented. In the article we motivate the foundation of OGSA over the service oriented architectural approaches (SOA and Web Services), as well as consider several novel grid standards, which reflect the specificity of remote resource operation.
