Industrial Information Grid (IIG) is a special kind of Grid system, the users of which exclusively own geographically distributed resources for Web service applications and try to decrease the lowest total cost of ownership while guaranteeing quality of service of applications. In this paper, we classify IIG as an extension to the general Grid problem. Our contributions are three-fold: first, we develop a unified management framework PhoenixG, which supports the collaboration of system administrators geographically distributed at different locations. Second, we propose a self-organizing algorithm that supports the initial establishment, daily management and exception processing of IIG. Finally, we evaluate the performance of system management and analyze the management overhead of PhoenixG.
