Windows virtual server hosting technology allows service providers to drop costs related to hosting and storing individual Web resources. It makes this possible by allowing a single machine to work as several different servers.
Physical bare metal server equipment can run nearly any modern general-purpose operating system when designed to work with this kind of technology. The server runs an instance of Microsoft Windows inside of a container without it realizing that it’s run inside of one.
The bare metal equipment could be running Linux, FreeBSD, Solaris or Darwin and the Windows software would be none the wiser. In fact, a server can run several instances alongside one another and Windows will still act as though each of these was an individual computer. Individual clients only rent as many virtual machines as they need to get the job done, thus they never pay for anything they don’t need.
