Desktop Virtualization: What It Is and Why Your Business Needs It

In today’s fast-paced, technology-driven world, businesses constantly seek ways to optimize their operations. One of the most powerful tools for achieving greater efficiency and flexibility is desktop virtualization.

Whether you’ve heard about virtual desktop infrastructure (VDI) or remote desktop services (RDS), desktop virtualization has become a go-to solution for businesses of all sizes. But what exactly is desktop virtualization, and why should your business consider it?

In this Mysterium VPN, we'll explore desktop virtualization's benefits and see how it can transform your business.

What Is Desktop Virtualization?

At its core, desktop virtualization is the technology that allows a computer’s desktop environment to be separated from the physical hardware (the client device) on which it runs. Client virtualization is a method of desktop virtualization that operates directly on the user's device, distinguishing it from server-based approaches.

In other words, virtual desktops can exist on a remote server or cloud-hosted virtual desktops, and users access them via the Internet or local system resources.

By utilizing virtual machines (VMs) and hardware virtualization technology, companies can create virtualized desktops that behave like traditional desktops but are more secure, flexible, and easier to manage.

How Does Desktop Virtualization Work?

Desktop virtualization relies on virtualization software to decouple the desktop environment from the underlying hardware. When users access a virtual desktop, they essentially log into a virtual machine running in a data center or on a host server.

This virtual desktop environment can run any operating system, such as Windows or Linux. These operating systems are hosted on virtual machines within a centralized server, allowing for distinct configurations for both persistent and nonpersistent virtual desktops.

By leveraging hardware virtualization, businesses can run multiple virtual desktops on a single physical machine or server hardware, allowing multiple users to access their virtual desktops simultaneously.

Virtual Desktop Infrastructure (VDI)

One of the most common forms of desktop virtualization is virtual desktop infrastructure (VDI). In a VDI environment, users can access their virtual desktops through a centralized server.

The VDI solution delivers virtual desktops to client devices through remote display protocols, such as Remote Desktop Protocol (RDP).

VDI offers businesses a scalable, flexible, and secure way to deliver virtual desktops to employees, regardless of their location.

By storing the desktop images on the server, users can access the same desktop environment from any internet-connected device, providing a consistent experience across different locations.

Types of Desktop Virtualization

Desktop virtualization comes in various forms, and businesses can choose a solution that fits their specific needs. Let’s take a look at the most common types of desktop virtualization:

Local Desktop Virtualization

In local desktop virtualization, the desktop operating system runs on the local device using desktop virtualization software. However, the desktop is isolated from the hardware, meaning users can run multiple desktops on a single machine.

This type of virtualization is great for development, testing, or specific applications that require dedicated hardware. Additionally, client virtualization, including presentation and application virtualization, offers significant benefits for resource management and application access across various devices.

Remote Desktop Virtualization

In remote desktop virtualization, the virtual desktop runs on a remote server, and users access it through the network. This is commonly used in enterprise computing resources to allow employees to access their user desktops remotely.

Remote desktop services (RDS) and Remote Desktop Session Host (RDSH) are common solutions for this type of virtualization.

Desktop as a Service (DaaS)

Desktop as a Service (DaaS) takes desktop virtualization to the cloud. Companies like VMware Horizon Cloud and Citrix Virtual Apps offer DaaS, where a third-party provider hosts the desktop virtualization infrastructure.

With DaaS, businesses don’t need to worry about maintaining their own server hardware or data center—everything is managed in the cloud.

Persistent and Non-Persistent Virtual Desktops

• Persistent virtual desktops: Users have their own dedicated virtual desktops that retain changes between sessions. This is ideal for employees who need personalized settings and access to specific apps.
• Non-persistent virtual desktops: A temporary virtual desktop that resets after each session, which is ideal for environments like customer service centers where multiple users share the same desktop image.

Operating systems are crucial in facilitating remote desktop virtualization by separating them from local devices and enabling centralized management in VDI setups.

Benefits of Desktop Virtualization

Now that we understand the basics let’s explore the benefits of desktop virtualization and why your business needs it:

Cost Savings

One of the most compelling reasons to adopt desktop virtualization solutions is the potential for cost savings. By reducing the need for expensive physical hardware, businesses can cut costs on client devices, upgrades, and maintenance.

Moreover, virtual desktops can be scaled up or down as needed, which allows businesses to pay only for what they use.

Enhanced Security

With desktop virtualization, businesses can centralize their security control and apply policies across all user desktops. Sensitive data is stored on a remote server rather than on individual machines, reducing the risk of data theft from lost or stolen personal devices.

Additionally, remote access to virtual desktops is secured with encryption and remote display protocols like RDP.

Centralized Management

Managing desktops across a large organization can be a nightmare. Desktop virtualization offers centralized management, allowing IT teams to quickly update desktop images, install applications, and manage users across the board.

Whether it’s pushing updates to multiple users or monitoring usage through connection broker software, virtualization streamlines desktop management.

Flexibility and Remote Work

As remote work becomes the new normal, desktop virtualization allows employees to access their virtual desktops from anywhere with an internet connection.

Whether they’re using personal devices like laptops or thin clients, employees can log into their virtual desktop environments and continue working just as they would in the office.

Improved Business Continuity

Businesses with virtualized environments can quickly restore desktop images and get their teams back to work in the event of a disaster or unexpected system failure.

With cloud computing and VDI in cloud computing, desktops are less vulnerable to physical damage, ensuring a higher level of business continuity.

Key Components of Desktop Virtualization

To fully understand how desktop virtualization works, it’s important to recognize its key components:

• Host Server: The central server that runs the virtual machines.
• Connection Broker Software: Manages user sessions, ensuring users connect to the correct virtual desktop.
• Operating System: Each virtual machine can run its own operating system, which can be Windows, Linux, or others.
• Virtual Server: A server that runs multiple virtual desktops or virtual apps on one physical server.
• Remote Display Protocol: Protocols like RDP and remote desktop protocol provide secure access to virtual desktops.
  

Choosing the Right Desktop Virtualization Solution

Not all desktop virtualization solutions are created equal. Whether you’re choosing local desktop virtualization, VDI environments, or cloud-hosted virtual desktops, the key is finding the right solution for your business’s needs.
