In today’s digital landscape, organisations constantly seek ways to enhance productivity, streamline operations, and provide flexible working solutions for their employees. Virtual Desktop Infrastructure (VDI) has emerged as a powerful technology that allows businesses to achieve these goals. Let us explore the concept of VDI, its benefits, and its impact on workplace productivity and flexibility.

What is VDI?

VDI is a virtualisation technology that enables the creation and delivery of virtual desktops to end-users over a network. It decouples the user’s desktop environment, including the operating system, applications, and data, from the physical device one is using. Instead of running applications and storing data on individual PCs or laptops, everything is hosted and managed on servers in a centralised data centre.

Its components

Host infrastructure

The host infrastructure consists of powerful servers, storage systems, and networking equipment that form the foundation for VDI. These components are responsible for hosting and delivering virtual desktops to end-users.


A hypervisor, also known as a virtual machine monitor, is a system that enables the creation and management of virtual machines (VMs) on physical servers. It allows multiple virtual desktops to run simultaneously on a single physical server, optimising resource utilisation.

Connection broker

The connection broker manages the connection between end-user devices and virtual desktops. It authenticates users, determines the appropriate desktop environment, and handles session management.

Virtual desktops

Virtual desktops are complete desktop environments encapsulated within virtual machines. They include the operating system, applications, and user settings. These desktops are accessed remotely by end-users using thin clients, web browsers, or other devices.

Its benefits

  • Flexibility. VDI enables employees to access their virtual desktops and applications from anywhere, using any device with an internet connection. This flexibility promotes remote work, Bring Your Own Device (BYOD) initiatives, and facilitates collaboration among geographically dispersed teams.
  • Simplified IT management. With VDI, IT administrators can centrally manage and update desktop environments, applications, and security policies. They can easily deploy new software, perform patches, and enforce security measures across all virtual desktops, reducing the burden of managing individual PCs.
  • Improved security. VDI enhances data security by keeping sensitive information in the data centre instead of on individual devices. This reduces the risk of data loss or theft due to physical device compromise. Additionally, IT administrators can implement access controls, encryption, and other security measures at the data centre level, ensuring better overall data protection.
  • Cost-efficiency. VDI can potentially reduce hardware and support costs. With virtual desktops hosted in the data centre, hardware upgrades and replacements become centralised, resulting in cost savings. Moreover, VDI allows for longer hardware lifecycles for end-user devices, as the heavy lifting is done by the servers in the data centre.
