This article is about what vdi refers to. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The full name of vdi is "Virtual Desktop Infrastructure", which means virtual desktop architecture; in VDI, hypervisor can segment servers into virtual machines, which in turn can host virtual desktops that users can access remotely from their devices.

Virtual desktop architecture "Virtual Desktop Infrastructure", referred to as VDI.

Virtual Desktop Infrastructure (VDI) uses virtual machines to provide and manage virtual desktops. VDI hosts desktop environments on centralized servers and deploys them for end users as requested.

In VDI, hypervisor can segment servers into virtual machines, which in turn can host virtual desktops that users can access remotely from their devices. Users can access these virtual desktops anytime, anywhere, on any device, and all processing is done on the host server. Users can connect to the desktop instance through a connection agent, which is a software-based gateway that acts as an intermediary between the user and the server.

VDI can be persistent or non-persistent. Each type has different advantages:

With persistent VDI, users connect to the same desktop every time and are able to personalize the desktop as needed, because changes are saved even if the connection is reset. In other words, desktops in persistent VDI environments behave exactly the same way as personal physical desktops.

By contrast, when using a non-persistent VDI, the user will connect to the generic desktop and any changes will not be saved. This VDI is generally simpler and cheaper because there is no need to maintain custom desktops between sessions. Non-persistent VDI is typically used in enterprises with a large number of task-oriented employees, or in enterprises with a large number of employees who perform limited repetitive tasks and do not require custom desktops.

Why choose VDI?

VDI has many advantages, such as user mobility, easy access, flexibility, and higher security. In the past, the high performance requirements of VDI made it not only expensive, but also difficult to deploy on traditional desktops, which deterred many enterprises. However, as more and more enterprises begin to adopt super-converged infrastructure (HCI), solutions that provide scalability and superior performance at lower cost emerge as the times require.

What are the advantages of VDI?

VDI is complex, which means that it is not necessarily an ideal choice for all enterprises, but it can provide many advantages for enterprises that use it. These include the following benefits:

Remote access: VDI users can connect to their virtual desktops anytime, anywhere, on any device, which allows employees to easily access all their files and applications and work remotely from anywhere in the world.

Cost savings: because the processing is done on the server, the hardware requirements for terminal devices are greatly reduced. Users can access their virtual desktops from old devices, thin clients and even tablets, reducing the need for IT departments to buy expensive new hardware.

Security: in a VDI environment, the data is on the server, not on the terminal client device. This protects data when the end device is stolen or invaded.

Centralized management: the centralized form of VDI makes it easy for IT departments to patch, update, or configure all virtual desktops in the system.

What is the purpose of VDI?

Although VDI can be used in a variety of environments, some application scenarios are particularly suitable for using VDI, including:

Telecommuting: with VDI, virtual desktops can be easily deployed and updated from a centralized location, so more and more companies are implementing VDI so that employees can work remotely.

Bring your own device (BYOD): VDI is an ideal solution for environments that allow or require employees to use their own devices. Because the processing is done on a centralized server, VDI supports a wider range of devices. In addition, it improves security because the data is located on the server rather than on the end client device.

Task-based work or shift work: non-persistent VDI is especially suitable for enterprises where a large number of employees use the same software to perform limited tasks, such as call centers.
