What is Desktop Virtualization?

Desktop virtualization is a technology that lets users simulate a workstation load to access a desktop from a connected device locally or remotely. The desktop environment and its applications are separated from the physical client device that used to access it. Desktop virtualization which is dependent on application virtualization, is a key element of digital workspaces.

How does desktop virtualization work?
Desktop virtualization can be accomplished in a various way, but the two most important types of desktop virtualization are determined by whether the operating system instance is local or remote.

Local Desktop Virtualization
Local desktop virtualization means the operating system runs on a client device using hardware virtualization, and all workloads and processing occur on local hardware. This type of desktop virtualization works well when users do not need a continuous network connection and can meet application computing requirements with local system resources. However, because this requires processing to be done locally you cannot use local desktop virtualization to share Virtual Machines (VMs) or resources across a network to thin clients or mobile devices.

Remote Desktop Virtualization
In a client/server computing system, remote desktop virtualization is a common use of virtualization. This allows users to run operating systems and applications from a server inside a data centre while all user interactions take place on a client device. This client device could be a laptop, a thin client device, or a smartphone. As a result, IT departments have more unified control over applications and desktops, and remote access to shared computing resources allows them to optimize the organization's IT hardware investment.

What is a virtual desktop infrastructure?
A popular type of desktop virtualization is virtual desktop infrastructure (VDI). VDI is a variant of the client-server model of desktop virtualization which uses host-based VMs to deliver persistent and non-persistent virtual desktops to all kinds of connected devices. With a persistent virtual desktop, each user has a unique desktop image that they can customize with apps and data, knowing it will be saved for future use. A non-persistent virtual desktop infrastructure allows users to access a virtual desktop from an identical pool when they need it; once the user logs out of a non-persistent VDI, it reverts to its unaltered state. Some of the advantages of virtual desktop infrastructure are improved security and centralized desktop management across an organization.

What are the benefits of desktop virtualization?

  • 1. Resource Management:
    By consolidating most of their computing in a data center, desktop virtualization allows IT departments to get the most out of their hardware investments. Since most of the intensive computing work is done in the data center, desktop virtualization enables enterprises to issue lower-cost computers and devices to end-users. By minimizing how much computing is needed at the endpoint devices for end-users, IT departments can save money by buying less costly machines.

  • 2. Remote work:
    IT administrators can better support remote staff with desktop virtualization because it gives them central control of how desktops are virtualized across an organization's computers. Instead of creating a new desktop for each user, IT can easily deploy a ready-to-use virtual desktop to that user's computer using desktop virtualization. Users can now communicate with the operating system and applications on the desktop from any place, and employees can have the same experience as if they were working locally. The user will log off and return the virtual desktop image to the shared pool until they've done using it.

  • 3. Security:
    IT administrators may use desktop virtualization tools to centralize security control over which users have access to which data and applications. Instead of having to manually uninstall all from that user's computers if their permissions change or they quit the business, desktop virtualization allows IT to automatically delete that user's access to their persistent virtual desktop and all of its data. Furthermore, since all company data is stored in the data center rather than on individual machines, a missing or stolen computer does not pose the same data security risk. If a laptop with desktop virtualization is stolen, there is no company data on the actual computer, reducing the possibility of a data breach.
