Virtual Machine Server
A VM (Virtual Machine) server hosts virtual machines that run a variety of operating systems and act as full computing platforms.
This is done through virtualization and emulation. VM servers are used for testing software in different environments without getting the hardware for the environments by software developers.
Doing this save the developers a lot of money and time and also prevents damage to hardware, which can occur when bugs are found in new software being developed.
Virtual machine servers allow for the deployment of a different combination of operating systems and software supported in the virtual environment, which is provided by the fully equipped and functional virtualization technology.
Administrators have access to a suite of management tools available in the virtual machine server allowing them to either increase or decrease resources allocated to the virtual machines.
