Operating System Level Virtualization

Operating system level virtualization (OS virtualization) is a server virtualization technology which involves altering of an operating system making it possible to run different applications that can be operated by different users working on a single computer at one time. The virtual operating systems work independently without interfering with one another even though they run on the same computer. The standard operating system is modified and adapted to operate as independent systems. These virtual systems are designed to obey the commands of the users who may run different applications at the same time on the machine. Each user request is handled individually by the virtual operating system. One advantage of the operating system level virtualization is that it will have minimal effect on the availability of the applications even at times of system upgrades and security patches being performed. Operating system Operating system virtualization facilitates migration of critical applications on to other virtual operating systems to ensure continuity of performance.
