Abstract: In the enterprise computing context, the strategies to apply grid technologies into the business environment are studied, and further grid enterprise, as a new enterprise operational mode, has been proposed. Based on the concept extension from computational grid to enterprise grid, the grid enterprise is defined and some relational theories and methodologies are built. In the end, the advantages of grid enterprise are detailed.
