The way people work has fundamentally changed. Hybrid and remote teams now expect to open their full desktop—apps, files, and settings—from a laptop at home, a tablet on the road, or a workstation at the office without missing a beat. Delivering that experience securely, regardless of device or location, is exactly the challenge that virtual desktop infrastructure was built to solve.
So, what is VDI? Virtual Desktop Infrastructure (VDI) is a technology that hosts desktop environments on a centralized server and delivers them to users over a network, so the desktop lives in a datacenter or the cloud rather than on the physical machine in front of you. For organizations embracing a Zero Trust approach, that distinction matters: by centralizing data and access in the cloud, VDI keeps sensitive information off endpoint devices and under centralized control, no matter where employees log in.
This guide breaks down how VDI works, the different ways it can be deployed, the benefits and use cases that make it worth considering, how it compares to related technologies, and the Microsoft solutions Ravenswood Technology Group implements to bring it to life.
What Is VDI (Virtual Desktop Infrastructure)?
Virtual Desktop Infrastructure (VDI) is a platform that lets organizations create, manage, and virtualize desktop environments and applications on centralized servers. Hosted in a datacenter or the cloud and delivered to users over a network, VDI separates the desktop from the physical device, so employees can work securely from anywhere.
The modern, cloud-based model takes this idea further. Instead of investing in racks of on-premises hardware, organizations can spin up virtual desktops in the cloud, scale them up or down as headcount shifts, and connect distributed teams across any device. Because the operating system, applications, and user data all reside centrally, IT gains a single point of control—and the foundation for a Zero Trust security posture that treats every access request as something to verify rather than assume.
The key takeaway is that the desktop is no longer tied to a specific piece of hardware. That decoupling is what makes everything else about VDI possible, and it starts with the technology working behind the scenes.
How Does VDI Work?
VDI runs on virtualization. At its core, a piece of software called a hypervisor allows a single physical server to host many isolated virtual desktops at once, each operating as if it were its own independent computer.
Key components of VDI
- Hypervisor — The virtualization layer that divides a physical server’s resources, allocating CPU, memory, and storage to each virtual machine.
- Virtual machines (VMs) — Each VM runs its own operating system, applications, and user settings, fully isolated from the others on the same host.
- Connection broker — The traffic controller that authenticates each user and routes them to an available desktop.
- Centralized storage — The datacenter or cloud-based storage where operating systems, virtual apps, and user data live.
- Client device — The laptop, tablet, thin client, or phone the employee uses; it needs little more than an internet connection.
- User profile management — The system that preserves a consistent, personalized experience—documents, preferences, and settings—across every session.
The VDI process in action
When an employee sits down to work, several things happen in seconds. First, the connection broker authenticates the user. Next, it assigns an available desktop based on that person’s profile and permissions. The user then interacts with their apps and files exactly as they would on a physical machine—opening email, editing documents, running line-of-business software. Throughout, IT manages every desktop centrally, applying updates, enforcing policies, and monitoring activity from one console rather than touching individual devices.
Types of VDI Deployments
Not all VDI environments are built the same way. Two decisions shape most deployments: whether desktops are persistent or non-persistent, and whether the infrastructure lives on-premises or in the cloud.
Persistent vs. non-persistent VDI
With persistent VDI, each user is assigned a dedicated desktop that saves their customizations, installed apps, and files between sessions. Logging in feels like returning to your own personal computer every time. This model suits knowledge workers and power users who need a tailored environment.
With non-persistent VDI, users connect to generic, single-use desktops that are spun up from a master image and destroyed at the end of each session. Nothing is retained on the desktop itself. This approach is highly cost-efficient and ideal for standardized roles—call centers, kiosks, or shift workers—where everyone needs the same baseline setup.
On-premises vs. cloud-based VDI
A self-managed datacenter deployment keeps the servers, hypervisors, and storage within your own facilities, giving you full control but requiring significant hardware investment, a stable and redundant internet connection, and ongoing maintenance.
A cloud-based deployment hosts the same environment on cloud infrastructure, and it has become the modern default for good reason. Cloud VDI offers pay-per-use pricing, elastic scaling to match demand, dramatically lower upfront hardware costs, and faster integration with other cloud computing services your organization already relies on. Just as important, you inherit the security investment of the cloud provider — physical data center security, platform patching, and hardening of the underlying infrastructure — rather than replicating all of it in your own environment. For most teams evaluating VDI today, the cloud is the natural starting point, and it sets the stage for the Microsoft solutions covered later in this guide.

Implementing VDI delivers a combination of operational, financial, and security advantages.
- Secure remote work — Users access multi-session Windows 10 and 11 desktops and critical apps from any internet-connected device, while data stays centralized and protected rather than scattered across endpoints.
- Centralized management — Deploy applications, push updates, and handle administrative tasks from one cloud console, simplifying desktop management across the entire organization.
- Cost efficiency — A predictable cost model, autoscaling, and the ability for multiple users to share a single virtual machine mean you pay only for the resources you actually use.
- Third-party access — Securely grant business partners and contractors access to specific applications and services without shipping or configuring physical hardware.
- Application compatibility — Run legacy or specialized software on virtual machines configured with exactly the right operating system, sidestepping compatibility headaches.
- Inherited platform security — With cloud VDI specifically, Microsoft secures and patches the underlying infrastructure, and services like Azure Virtual Desktop integrate natively with Microsoft Entra ID conditional access, multifactor authentication, and Microsoft Defender. You get enterprise-grade controls without building and staffing them yourself.Â
Beyond these core wins, VDI also delivers a consistent employee experience across every device, faster onboarding for new hires, strong data protection in Bring Your Own Device (BYOD) scenarios, and simplified compliance thanks to centralized data and access controls.
Common VDI Use Cases
VDI is most valuable when you can match it to a real business need. Common scenarios include:
- Remote and hybrid work — Give distributed teams secure access to a full desktop from wherever they happen to be.
- Bring Your Own Device (BYOD) — Let employees use personal devices while keeping corporate data off the hardware itself.
- Contractors, seasonal, and temporary workforces — Provision and decommission desktops on demand as your headcount fluctuates.
- Highly regulated industries — Help finance, healthcare, and government organizations keep sensitive data centralized and auditable.
- Business continuity and disaster recovery — Keep teams productive during disruptions, since desktops and data live safely in the cloud rather than on vulnerable local machines.
- Running legacy or specialized applications — Host older or niche software on purpose-built virtual machines without disrupting the rest of your environment.
- Privileged Access Workstations (PAWs) – PAWs can be hosted as VDI systems instead of physical which provides an easy and cost-effective option to provide secure admin-only systems for admin tasks.
As you read through these, the question to ask is straightforward: does one of them describe your situation? If so, VDI is worth a serious look.
VDI vs. Related Technologies
VDI is often confused with adjacent technologies. Here is how it compares.

The short version: a VPN brings the network to your device, RDS shares one server among many people or a dedicated VM per user if you configure it to, and DaaS is VDI someone else runs for you. VDI itself gives each user a dedicated, centrally managed desktop.

VDI FAQs
What does VDI stand for? VDI stands for Virtual Desktop Infrastructure. It refers to the technology that hosts desktop operating systems on centralized servers and delivers them to users as virtual desktops over a network.
What is an example of VDI? Azure Virtual Desktop and Windows 365 are two widely used examples. Both let organizations deliver a secure Windows desktop experience from the cloud to virtually any device.
What is the difference between VDI and a virtual machine? A virtual machine is a single software-based computer running its own operating system on shared physical hardware. VDI is the broader infrastructure that creates, brokers, and delivers many of those virtual machines to end users as accessible desktops. In short, VMs are the building blocks; VDI is the system that turns them into usable desktops.
What is the difference between VDI and DaaS? With VDI, your organization owns and manages the underlying infrastructure. DaaS (Desktop as a Service) delivers the same virtual desktop experience as a fully managed cloud subscription, so the provider handles the servers, maintenance, and scaling on your behalf.
Is VDI the same as remote desktop? Not quite. Remote desktop tools typically connect users to a shared session or a specific machine. VDI provisions dedicated virtual desktops for each user from a centralized pool, with centralized management, scaling, and security built in. Users may then use remote desktop to access their VDI VM.
Conclusion
VDI delivers secure, centralized, and flexible desktops that are well suited to the demands of modern hybrid work. By separating the desktop from the device and centralizing data and access in the cloud, it lets your team work from anywhere while IT maintains control and upholds Zero Trust principles.
