What is a Virtual Desktop Infrastructure (VDI)?

A Virtual Desktop Infrastructure (VDI) is a technological solution that makes it possible to create and manage virtual desktops for users via a central server. VDI allows users to access their desktop environment and applications from various devices, such as laptops, tablets and thin clients, over the Internet or a local network.

The VDI concept revolves around separating the user interface (desktop) from the physical hardware. Instead of the desktop being hosted on a local computer or laptop, it is hosted on a powerful server in the data center. The user connects to the virtual desktop on the server via a thin client (a lightweight device with limited processing power) or another device.

How does VDI work?

1. Virtual Machines (VMs): In a VDI environment, multiple virtual machines are created on a powerful server in the data center. Each virtual machine functions as a separate desktop environment and has its own operating system and installed applications.

2. Connect: Users can connect to their assigned virtual desktops through a VDI client software on their device. This client software acts as a bridge between the user and the virtual desktop on the server.

3. User experience: Once users are connected, they can use their virtual desktop as they would on a local machine. They can access their files, applications and settings as if they were working directly on their device.

Main advantages of VDI:

1. Centralization: VDI centralizes desktop management, making it easier for IT teams to perform updates, patches, and software deployments. This can reduce IT maintenance costs.

2. Flexibility: Users can access their virtual desktops from any device and location, enabling mobility and flexible working.

3. Security: Because the desktop environment and data reside on a secure server, VDI can help improve security and data protection.

4. Cost savings: With VDI, organizations may be able to save costs on hardware because less powerful devices such as thin clients can be used.

5. Rapid provisioning: New virtual desktops can be quickly created and assigned to users, making it easier to set up new employees and create temporary desktops for specific projects.

VDI is widely used in business environments, educational institutions, healthcare and other industries where flexibility, security and efficient management of desktop environments are essential. It is a powerful technology that enables organizations to create a modern, secure and scalable work environment for their users.
