Build your own "cloud"
With virtualisation technologies such as the Microsoft HyperV or the following, we can quickly and efficiently deploy a whole virtualised environment ready for any business critical applications.
With one physical machine you will be able to roughly run three, even four servers at any one time. Obviously the more higher specification the physical host is, the more virtual servers you will be able to have running at any one time.
A "bare-metal" alternative to the Microsoft Hyper-V Server with better overall compatibility for Linux / Unix operating systems.
