What is IT Virtualisation?
IT virtualisation in cloud computing allows us to virtualise your
servers, storage, or other physical hardware or data centre
resources, allowing them to provide numerous services such as
infrastructure, software, and platforms.
It uses software to create an abstraction layer over computer
hardware that allows the hardware elements of a single
computer—processors, memory, storage and more—to be divided into
multiple virtual computers, commonly called virtual machines (VMs).
Each virtual machine runs its operating system (OS) and behaves like
an independent computer, even though it runs on just a portion of
the underlying computer hardware.
Historically, businesses have run most of their user software on
desktops/laptops with the software installed locally. Virtualisation
moves this responsibility from the end user desk to one central
point. It allows for a lighter footprint but also ensures that
software is deployed correctly and updated centrally on the most
up-to-date equipment, always.
