The virtualization of the PC server, rather than run on the Windows Server or Linux server OS of direct server machine, to operate the first virtualization software on the server machine, to move the server OS on it. You can run multiple server OS on one of the virtualization software. This is the first feature of the server virtualization, it is merit. Physical servers machine even if there is only one, it is as if to a plurality of computing environments, such as if the server machine is capable of producing virtually. We call each one of this virtually created the computing environment as a "virtual server" or "virtual machine". A virtual server, in other words, "and the OS, that one or more of the applications running on the" is. Need to you want to do ultimately moves the multiple applications simultaneously, recent OS so also for even server desktop multitasking, single or not the be able to run multiple applications on the OS, and a plurality of Do not need not to move the virtual server bother, it will occur question. It is not a mistake, but do not know emergency and if the desktop PC, for the case of a server that is running a stable and software, have been made often to move the only application one on a single server. Toka different software components of the version required for each application, then it has operational problems, such as there is an incompatible OS patch, from the cut of convenience when the software failure occurs, separate for each application We want to give the environment. Image One utilization efficiency of tend to reason low of server can be found here. Each time you will have to build some business system (application) of a company, first procure a new server. Thus only the number of business systems is born situation that there is a server. According to one study, of each server is not used only average dozen% Speaking at the utilization of the CPU. Using the technology of server virtualization, this until the OS and applications that were running on separate physical servers, you can be a virtual server. And if moving the multiple virtual servers on each physical server, and you will move the business system of the same number with a small number of physical servers. Is progressing around the large companies' server consolidation "(sometimes called" server consolidation ") is to reduce the server's number by utilizing the server virtualization technology has become one of the main tasks You.
