A central controlled distributed scalable virtual machine (“CCDSVM”) of the present invention can be expanded across network domain such as LAN, WAN, Intranet and Internet. A larger number of computing systems (computing devices) in the CCDSVM can be organized into multiple groups (service pools) within a multi-layered hierarchy. The CCDSVM includes at least a top level control computing device to control and organize a management pool that includes a plurality of middle level control computing devices, where each middle control computing device can control a corresponding service pool of a plurality of computing devices. Therefore, the CCDSVM can provide a plurality of users, each with different credential and privilege, web based accessing the CCDSVM at different levels.
