When you have a machine with just BIOS (basic input-output system) on it, one way to load an Operating system is to use a bootable thumb drive, similar to the way you work with a laptop. However, installing OS on remote systems in data centers that are present in remote locations might not be feasible. Installing an operating system over the network directly to the computer’s hardware is known as bare metal provisioning.

Razor uses the characteristics of bare metal hardware as well as user-provided data to make provisioning decisions.The idea around Razor is to be able to consume the physical, freshly racked servers into a virtual model.
