Resource discovery in Grids and other distributed environments: States of the art

The emerging Grid technologies hold out the promise of a global information channel that is far more powerful and uniquely distinct from the existing internet framework. This paper addresses the issue of resource discovery in Grids and aims to review the current state-of-the-art and provide an up-to-date taxonomy of existing Grid resource discovery methods. The various resource discovery methods, techniques and approaches are critically discussed, and recommendations are made with respect to practical implementation and directions of future research in Grid resource discovery.
