The Anatomy of the Grid: Enabling Scalable Virtual Organizations Ian Foster Mathematics and Computer Science Division, Argonne National Laboratory Department of Computer Science, The University of Chicago, USA foster@{mcs.anl.gov,cs.uchicago.edu} http://www.mcs.anl.gov/~foster The term “the Grid” was coined in the mid1990s to denote a proposed distributed computing infrastructure for advanced science and engineering [4]. Considerable progress has since been made on the construction of such an infrastructure (e.g., [1, 2, 6, 7]) but the term “Grid” has also been conflated, at least in popular perception, to embrace everything from advanced networking to artificial intelligence. One might wonder whether the term has any real substance and meaning. Is there really a distinct “Grid problem” and hence a need for new “Grid technologies”? If so, what is the nature of these technologies, and what is their domain of applicability? While numerous groups have interest in Grid concepts and share, to a significant extent, a common vision of Grid architecture, we do not see consensus on the answers to these questions. My purpose in this talk is to argue that the Grid concept is indeed motivated by a real and specific problem and that there is an emerging, well-defined Grid technology base that solves this problem. In the process, I develop a detailed architecture and roadmap for current and future Grid technologies. I also argue that while Grid technologies are currently distinct from other major technology trends, such as Internet, enterprise, distributed, and peer-to-peer computing, these other trends can benefit significantly from growing into the problem space addressed by Grid technologies. The real and specific problem that underlies the Grid concept is coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations . The sharing that we are concerned with is not primarily file exchange but rather direct access to computers, software, data, and other resources, as is required by a range of collaborative problem-solving and resource-brokering strategies emerging in industry, science, and engineering. This sharing is, necessarily, highly controlled, with resource providers and consumers defining clearly and carefully just what is shared, who is allowed to share, and the conditions
