This paper argues that the technology of Grid computing has not yet been adopted in commercial settings due to the lack of viable business models. While in academia Grid technology has already been taken up, the sharing approach among non for-profit organizations is not suitable for enterprises. In this paper, the idea of a Grid market is taken up to overcome this Grid adoption gap. We propose a framework for building up a Grid market and identifies the associated economic and technical challenges. Based on this framework, we identify a catalogue of possible market mechanisms which offer a promising fit to the Grid environment’s characteristics and which may thus help to carry the idea of Grid markets from theory to practice.
