Virtualization is a technology that divides physical server resources among multiple users and applications. The best example to explain the idea of virtualization is an apartment building. A country house owner has to take care of water and power supply, wood harvesting and organizing heating. Residents of the apartment building do not have to care about public utilities, because they provided by a city. A server is a piece of equipment that hosts data. A physical server is like a country house. However, it is possible to make an apartment building from it — this is where you'll need virtualization. With private servers, many people use the same physical server, but everyone has his own independent amount of computing resources. Therefore, different virtual servers hosted on the same physical server may have different operating systems, regardless of OS family.
