What is desktop virtualization, how does it operate, types of desktop virtualization, desktop virtualization versus server virtualization, and more will all be covered in this blog.
What is desktop virtualization?
Desktop virtualisation is a cutting-edge technology that separates the desktop environment which includes the data, apps, and operating system from the actual computer. Detaching the tools from the machine itself enables a very accessible and adaptable computing system in which the user’s desktop is located on a server and accessible from any location.
The idea of desktop virtualisation acts as a link in the computer industry between the conventional, physical limitations of hardware and the boundless possibilities of virtual workspaces. By enabling users to access their personal desktop space remotely, it reflects the change in how users view and utilise computers and offers freedom and mobility that are unprecedented in the traditional computing model.

Everyone are no longer dependent on any one place or gadget. Rather, nous welcome the flexibility to work, learn, and communicate in a digital environment that adapts to the needs. By removing the constraints imposed by conventional IT infrastructure, desktop virtualisation marks a substantial advancement towards computing paradigms that are more agile, resilient, and user-centric.
How does it work?
Desktop virtualization fundamentally works by using a centralized server to host a desktop operating system. With this configuration, numerous users can concurrently access their own virtualized desktop instances. A user’s desktop instance running on the server is linked to them when they log in. Regardless of the hardware utilized, this connection can be established through a variety of devices, including tablets, smartphones, thin clients, and classic PCs. All of these devices provide a smooth computing experience.

There are two main ways that this adaptable solution operates: locally and remotely.
Local desktop virtualization
By utilising the local system resources, local desktop virtualization allows the operating system of a computer to operate directly on a client device. This method works best for people whose computing needs are met by the local system and who don’t need a continuous network connection. However, local desktop virtualization does not enable the sharing of external resources, such as thin clients and mobile devices, or virtual machines (VMs) over a network when processing is done locally.
Remote desktop virtualization
However, server-based settings are where remote desktop virtualisation excels. It allows users to interact with systems and apps on personal devices like laptops or smartphones while they are housed within the protected boundaries of a datacenter. By giving remote access to shared computing capacity, this configuration enables businesses to extend their hardware investments while giving IT teams the benefit of centralised management.
Types of desktop virtualization
Desktop virtualization comes in two flavors: hosted and client.

Hosted virtualization
The process of hosting desktop environments in the cloud or on a central server is known as hosted desktop virtualisation. Several varieties can be distinguished within this category:
Desktops and apps can now be accessed whenever and wherever needed to virtual desktop infrastructure (VDI). Each user is given a dedicated desktop instance on the server with virtual desktop architecture, allowing them to access their instance from any device. Although this approach gives a high level of performance and personalization, it uses a lot of server resources.
Multiple users can access a shared desktop and apps from a distant server to remote desktop services (RDS). A single operating system instance is shared by several users with RDI, which maximizes resource utilization but reduces personalization.
A third-party provider of hosted desktop services is called Desktop-as-a-Service (DaaS). Businesses can provide employees with individualized desktops from almost any device at any time with desktop-as-a-service. With this cloud-based service, the provider assumes responsibility for handling the backend tasks of data storage, backup, security, and upgrades. Since hybrid environments are becoming more prevalent, DaaS provides scalability and flexibility, which makes it a desirable choice for small and medium-sized enterprises.
Client virtualization
Client virtualization, the alternative form of desktop virtualization, takes a different tack by emphasizing the direct execution of the virtualization technology on the user’s device. Two categories can be distinguished within this category:
By separating the application layer from the graphical user interface, presentation virtualization allows an application to run on a server and be displayed on the user’s device. In situations where a large number of users must access a standardized set of apps and where central control and management of these applications are essential, it can help with resource efficiency and management.

Through application virtualization, an application is isolated from the computer hardware on which it runs. Applications can operate without being installed on the operating system directly to application virtualization. This approach makes it easier to deploy and administer applications and works well in situations where they must be accessed remotely across a variety of devices.
Desktop virtualization vs. Server virtualization
| Feature | Desktop Virtualization | Server Virtualization |
|---|---|---|
| Definition | Abstracts OS and apps from a physical thin client | Abstracts a server OS and apps from the physical machine |
| Purpose | Provides virtual desktops to end users | Creates multiple virtual servers on a physical server |
| Hardware Dependency | Hardware-independent, accessible from any device | Runs on physical server hardware |
| Usage Scenario | Used in Virtual Desktop Infrastructure (VDI) and cloud-based desktop services | Used in data centers for efficient resource utilization |
| OS Requirement | Each user can have a different OS environment | Multiple VMs on a single server, each with its own OS |
| Performance | Depends on network bandwidth and latency | Depends on server resources (CPU, RAM, storage) |
| Scalability | Can be scaled dynamically, but requires high bandwidth | Highly scalable by adding more virtual servers |
| Security | Centralized management improves security | Isolation between virtual servers enhances security |
| Bandwidth Requirement | High (due to remote access and streaming) | Low to moderate |
| Cost Efficiency | Reduces endpoint hardware costs | Reduces the need for multiple physical servers |
