The days of purchasing separate servers for your file server, mail server, web server, application server, and domain controller are over.

Between the high replacement cost of faulty servers and limited functionality (servers that could only output a single function), virtualization has become a more reliable and efficient alternative option. Virtualization technology separates the hardware resources (RAM, Hard Drive, CPU) from the Software (Operating Systems) and acts as the middle man between the two. This technology can be used to virtualize Servers, Workstations, Storage, and even Networking appliances. The most common use of this technology is the server space. Instead of installing one operating system on a physical server, you can now install several operating systems on a physical server.
