A virtual server, also known as a virtual machine, is a software-based emulation of a physical computer created by a hypervisor. It runs independently within a virtualised environment on a physical server, allowing multiple virtual servers to share resources efficiently. Virtual servers provide a wealth of benefits such as isolation, flexible resource allocation, snapshot and cloning capabilities, easy migration, and scalability. They contribute to cost savings, energy efficiency, and improved management in data centres and cloud computing environments.

What is a Hypervisor?

A hypervisor, also known as a Virtual Machine Monitor (VMM), is software or firmware that creates and manages virtual machines (VMs) on a physical computer. The primary purpose of a hypervisor is to enable multiple operating systems to run concurrently on a single physical machine, each within its isolated virtual environment.
