Abstract: A computing system includes a physical server having a single instance of an operating system; and a plurality of virtual environments running on the physical server and directly supported by the single instance of the operating system. Each virtual environment responds to requests from users and appears to the users as a stand-alone server having its own instance of the operating system. Each virtual environment has a plurality of objects associated with it and supported by the operating system. Some of the objects are private and other objects are shared between multiple virtual environments. One virtual environment cannot access private objects of another virtual environment.

Abstract: A computer cluster for providing hosting services includes a plurality of nodes, and a control center coordinating activity of the nodes. Each node includes a plurality of virtual servers such that each virtual server responds to user requests and appears to the user as having its own operating system. Multiple virtual servers running on the same node share the same host operating system and root application software of the node.

Abstract: Method of efficient utilization of a single hardware system with single operating system kernel wherein a virtual environment, functionally equivalent to a full-featured operating system box, is provided to an end user without emulation of hardware, dedicated physical memory or another hardware resource. Such method is realized by separation of user processes on the level of namespace and on the basis of restrictions implemented inside the operating system kernel. Each virtual environment is invisible to other virtual environments within the system and has a completely independent root file system.

Abstract: The present invention is a system and method for utilization of computer clusters with automatic configuration and virtual environments integrated with a distributed file system as a hosting service providing platform. The virtual environment of the present invention emulates no hardware and is essentially a personal protected machine with an independent operating system that functions as a separate workstation or server.
