The operation efficiency of a large scale distributed computing system in a world wide web environment is critical to any enterprises, ISP, or ASP due to a larger number of individual computing units in the distributed computing system are required to be operated. A multi-layered server structure with deployment of middle level control server for the distributed computing system of this invention can lead to a more secure and efficient computing environment for managing and access the larger number of computing units in the distributed computing system due to the middle level control server can effectively shared the burden of controlling the larger number of the computing units from a centralized control server of the distributed computing system.
