Desktop Virtualisation

Desktop Virtualization Defined

Desktop virtualization, sometimes referred to as client virtualization, is defined as a virtualization technology that is used to separate a computer desktop environment from the physical computer. Desktop virtualization is considered a type of client-server computing model because the virtualized desktop is stored on a centralized, or remote, server and not the physical machine being virtualized. 

Desktop virtualization "virtualizes desktop computers" and these virtual desktop environments are "served" to users on the network.  Users interact with a virtual desktop in the same way that a physical desktop is accessed and used. Another benefit of desktop virtualization is that is lets you remotely log in to access your desktop from any location.

One of the most popular uses of desktop virtualization is in the data center, where personalized desktop images for each user is hosted on a data center server.

As technology to virtualize operating systems improves as a result of server systems, it is making progress towards home and personal use. This is much of the driving force in desktop virtualization. The constantly increasing power and availability of computer hardware has also been beneficial. Previously cost-prohibitive hardware to support simultaneous multiple operating systems has become affordable for anyone looking into a computer purchase.

Common Types of Virtual Desktops

VDI (Virtual Desktop Infrastructure -- or Interface) is a popular method of desktop virtualization. This type of desktop virtualization uses the server computing model, as the desktop virtualization in this scenario is enabled through hardware and software. VDI hosts the desktop environment in a virtual machine (VM) that runs on a centralized or remote server.

There are also options for using hosted virtual desktops, where the desktop virtualization services are provided to a business through a third-party. The service provider will provide the managed desktop configuration, security, and storage-area network.

Benefits of Desktop Virtualization

Desktop virtualization offers advantages over computers operating as individual units as each virtual desktop will not require its own hardware, operating system and software. Also, using desktop virtualization lower cost of deploying applications and will reduce downtime in the event of a server or hardware failure.
