What is Virtual desktop Infrastructure (VDI)?

A virtual desktop infrastructure is a technology used to create a virtualised environment on a remote server setup. This is a form of desktop virtualisation.

VDI separates the servers into a number of virtual desktops that the user can access remotely through their devices. In the past, for business’ to input high-security measures, would have been costly which posted a barrier for them however VDI gives a low-cost solution for this.

What are the benefits of VDI?

VPI doesn’t just benefit the people using it but it also benefits the environment, I’ve listed 5 top benefits you will get with a virtual desktop infrastructure.

1. Access

With workplaces being made more mobile than ever, with VDI you are able to access your desktop from anywhere, day or night it gives you the freedom to work remotely stress-free

2. Flexibility

Enhance flexibility for the business and workers. As long as you can access the internet you can use your preferred device to access the VDI

3. Manageability

As VDI replaces PCs it becomes much more manageable to deal with, especially in size. The development, management, and replacement of the endpoints become much easier (Endpoints can be laptops, tablets mobile devices).

4. Security

If your device is stolen or damaged there is a high chance your data will be lost. However in this case your operating system, applications, and data are stored in a remote data center with high-level security. If anything does happen to your device your data won’t be lost as you can access your desktop from any other device.

5.Cost Saving

Less IT resources are required, the main cost-saver will be eliminating the cost of the hardware. Using VDI services from a cloud provider lets you access your desktop even if your hardware is outdated.

How does VDI work?

The hypervisor utilises and sections servers into virtual machines that in turn host virtual desktops that users access remotely from their device. 

The basic components needed:

  • Hypervisor

         The software that separates the operating system from its hardware, creating a virtualised environment that then can be divided into a number of virtual machines. 

  • Virtualisation

         The technology that divides the system into multiple different layers.

  • Connector

          This is the piece that manages the connection between the user and the endpoint (laptop, tablet, phone, etc) and responsible for the authentication of the users. 

  • Desktop pools

         A group of similar desktops that are hosted on virtual machines that can be configured according to a specific function. 

  • Application virtualisation

         This is a very important piece of Virtual desktop infrastructure it’s used to create a virtualised application image and duplicate it to all the virtual desktops in a desktop pool.
