History of virtualization

The term “virtualization” has been around since the 1960s. However, because there were no personal computers in those days, virtualization did not become a reality until the late 1990s.

Companies realized then that they could save money by moving from a physical to a virtual platform.

You or your company might be interested in virtualization because it can:

  • Save you money by reducing the number of servers consuming energy, and by costing less to purchase and maintain;
  • Make management, control and inspection of VMs much easier than with traditional servers;
  • Give you a flexible environment for various tests—and more!

Microsoft could not ignore the virtualization trend. Microsoft introduced Hyper-V as a virtualization platform in 2008, and it continued to release new Hyper-V versions with new Windows server versions. So far, there are a total of four versions, including Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2 and Windows Server 2008.

Hyper-V is a hybrid hypervisor, which is installed from OS (via Windows wizard of adding roles). However, during installation it redesigns the OS architecture and becomes just like a next layer on the physical hardware.
