Virtual Desktop Infrastructure (VDI): What Is it & How It Works - V2 Cloud

What Is Virtual Desktop Infrastructure (VDI)?

VDI stands for Virtual Desktop Infrastructure, a technology that allows users to create virtualized desktop environments on a remote server setup. It transforms the way we interact with computers, enclosing both the operating system and its suite of applications within a software package. 

These software-defined desktops then run as distinct instances on the server, which can be divided into numerous virtual desktops, each accessible to users remotely from their own devices.

This solution offers unparalleled flexibility, enabling you to access your data from virtually anywhere and at any time. Whether you’re using a laptop, desktop computer, smartphone, or tablet, VDI ensures your data is within reach. What’s more, your data benefits from instant, robust backup through the remote server infrastructure.


VDI goes beyond convenience and offers enhanced data security. To shield your information from threats, multiple layers of protection include:

  • Multi-factor authentication
  • Data encryption
  • Password safeguards
  • Intrusion detection
  • Prevention systems


Notably, VDI is a cost-effective solution, eliminating the need for physical IT infrastructure. Gone are the days of hiring IT staff or budgeting for infrastructure maintenance to enjoy VDI’s benefits. Additionally, software updates become easy as applications run seamlessly on virtual desktops, saving you from software update expenses.


How Does VDI Work?

The primary goal of Virtual Desktop Infrastructure (VDI) deployment is to enable swift, effortless, and secure access to a virtual desktop environment. This technology empowers end-users to access their full desktop experience remotely, from any location, using any device – including cost-effective thin clients and mobile devices.


Despite the variety of VDI solutions, they all adhere to core operational principles:

  • Centralized Server Operation: VDI is centered around a server, typically housed in a data center. This server runs Virtual Machines (VMs), each of which hosts a virtual desktop.
  • Operating System Imaging: Within these VMs, each virtual desktop functions on an image of an Operating System (OS), commonly Microsoft Windows or Windows Server.
  • Server Capacity and VM Instances: The number of Virtual Machines that a server can accommodate depends on its hardware capabilities. Advanced servers can host multiple VM instances simultaneously, optimizing resource use.
  • Remote Access and Connectivity: End-user devices gain access to their virtual desktops through a connection to this server, typically via cloud technology. It’s crucial for this connection to be stable and consistent to ensure uninterrupted access to the virtual desktops.
  • Hypervisor Software Role: The creation, operation, and management of these VMs are overseen by hypervisor software. This software ensures that each VM runs its own distinct virtual desktop environment.
  • Connection Broker Functionality: Acting as an intermediary, the connection broker, an integral part of the VDI software layer, efficiently matches each end-user with the most suitable virtual desktop. This process is vital for balancing load and optimizing user experience.


Through these principles, VDI delivers a robust, flexible, and secure computing solution, adaptable to a wide range of user needs and business scenarios.


Persistent VDI vs Non-persistent VDI

Virtual Desktop Infrastructure bifurcates into two distinct models, each catering to different user requirements: Persistent VDI and Non-persistent VDI.


Persistent VDI: Tailored and Consistent

Persistent VDI mirrors the experience of using a personal, physical desktop. In this model, users reconnect to the same desktop environment with every session. This consistency allows for extensive customization and personalization – changes and preferences are retained, even after the user disconnects. 

Persistent VDI is ideally suited for users who require a constant and customized desktop experience, mirroring the familiarity and personalization of a traditional PC.


Non-persistent VDI: Generic and Economical

In contrast, Non-persistent VDI offers a more universal and transient desktop experience. Users connect to a generic desktop environment, and no personal changes or customizations are saved between sessions. 

This model is typically more cost-effective and straightforward to manage, as it eliminates the need to preserve individual user settings. Non-persistent VDI is particularly effective in environments where users perform a limited range of tasks and do not require a personalized desktop, such as in settings with high employee turnover or where users share workstations.


Technology Behind Virtual Desktop Infrastructure

Virtual Desktop Infrastructure relies on several key components to create a flexible and efficient virtualized desktop environment. The following fundamental elements lay the foundation for the seamless operation of VDI systems:



At the core of VDI is virtualization. This concept involves the creation of virtual computers or desktops, allowing for the efficient sharing of computational power and hardware resources. It accomplishes this by establishing a virtualization layer that sits between the physical hardware components and the end-user. This layer ensures that multiple virtual desktops can coexist on the same server, efficiently utilizing available resources.



A critical component of VDI is the hypervisor. This software program plays a pivotal role in the virtualization process by creating a virtualized environment that separates the operating system and its applications from the underlying hardware resources. Essentially, the hypervisor acts as a mediator, enabling multiple virtual desktops to run on the same physical server while keeping them isolated and secure.


Connection Broker

To enable seamless remote access to virtual desktops from various devices, a connection broker is employed. This software program serves as a vital intermediary, allowing end-users to connect to their designated virtual desktops, regardless of the device they are using. It manages user sessions, ensuring a smooth and consistent experience across different platforms.


Desktop Pools

Desktop pools are collections of virtual desktops that share identical configurations, including the operating system, storage settings, and installed applications. Desktop pools simplify management and deployment, making it easier to scale VDI environments and maintain consistency across virtual desktop instances.


Application Virtualization

In VDI, application virtualization plays a crucial role in streamlining the deployment and management of software applications. This technology involves creating virtualized application images that can be replicated across various virtual desktop pools. By decoupling applications from the underlying operating system, updates and changes can be applied more efficiently, reducing the complexity of software management within the VDI ecosystem.


Difference Between VDI VS Desktop Virtualization

While the terms “Virtual Desktop Infrastructure” and “Desktop Virtualization" are frequently used synonymously, they represent distinct concepts within the domain of virtual computing.

Desktop Virtualization represents a broad category encompassing any technology designed to abstract a desktop operating system (OS) and its environment from the physical hardware it runs on. This term is an umbrella for various technologies that enable users to access and operate a desktop environment remotely.

On the other hand, VDI is a specialized form of desktop virtualization. It specifically refers to the practice of hosting a desktop OS within a virtual machine (VM) on a centralized server. VDI is one method among several in the broader field of desktop virtualization, which also includes solutions like RDS (Remote Desktop Services) and DaaS (Desktop as a Service). 

Each of these technologies offers different approaches and capabilities within the scope of desktop virtualization.


Difference Between VDI VS VM (Virtual Machine)

Similarly, VDI is often confused with VMs (Virtual Machines).

Virtual Machines are the foundational technology that enables the existence of VDI. A VM is essentially a software emulation of a physical computer. It operates by partitioning a single physical server into multiple virtual servers, each capable of running its own independent OS. This partitioning is managed by a hypervisor, which allocates hardware resources among the various VMs. 

VMs are versatile and can be used for a range of purposes, including, but not limited to, hosting a virtual desktop OS in a VDI deployment.

VDI, in contrast, is a specific application of VM technology, focused on delivering and managing desktop environments. While VMs create the virtualized infrastructure, VDI is the framework that leverages this infrastructure to provide end-users with access to a virtual desktop. 

This distinction highlights VDI’s role as a conduit for delivering desktop services via VMs, rather than just being the virtualization technology itself.


Main Benefits of a Virtual Desktop Infrastructure

Businesses are constantly seeking innovative solutions to boost productivity, streamline operations, and enhance security. VDI can achieve all these goals and more. Let’s delve into the main benefits of VDI and explore how it can revolutionize the way your business operates.
