Grid Computing with Globus : An Overview and Research Challenges

The Open Grid Forum (OGF) is an organization that resulted from the merger of the Global Grid Forum (GGF) and the Enterprise Grid Alliance (EGA). GGF was an international organization that started in 1999, with the focus on the development of open standards for grid soft ware interoperability, common practices, agreements and other related issues and proposed several specifications with the help of several working groups. The grid project started with the aim of using high -end computational recourses, networks, databases and scientific instruments owned and managed by multiple organizations. Globus [5] is one of the most successful projects in grid computing to test these specifications. Although it could overcome many technological barriers, many are still remains as open questions. In this article we discuss about grid, Globus Toolkit and present some of technical challenges the grid community faces. Further, we provide future research directions in Grid Computing.
