VDI stands for Virtual Desktop Infrastructure. VDI is a technology that allows you to create a virtualized desktop environment on a remote server set up. The operating system and its applications are encapsulated into a software package and run as an instance on the server. The server is segmented into multiple virtual desktops and the users are allowed to access these virtual desktops remotely through their devices.

VDI technology allows you to access your data from anywhere at any time. VDI also allows you to access your data from multiple devices such as laptops, desktop computers, mobile phones, and tablets. In a VDI, your data will be instantly backed up through the remote server.

VDI helps you to keep your data secure through security measures such as multi-factor authentication, data encryption, password protection intrusion detection, and prevention system. VDI is a cost-effective solution as it does not require physical IT infrastructure. You do not need to have an IT staff or infrastructure maintenance cost to utilize a VDI. Three is no software update cost as the applications run on virtual desktops.

The basic components of a VDI

  • Virtualization – the creation of virtual computers to share computation power and hardware resources more efficiently by creating a virtualization layer between the hardware components and the user.
  • Hypervisor – a software program that separates the OS and its applications form the underlying hardware resources by creating a virtualized environment.
  • Connection broker – a software program that allows the end-users to connect to a remote virtual desktop using different devices.
  • Desktop pools – a set of virtual desktops with an identical configuration of OS, storage, and applications.
  • Application virtualization – the technology used to create a virtualized application image and replicate it to all the virtual desktop pools.
