The way we work has changed fundamentally over the last few years. The traditional image of an office worker tied to a mahogany desk and a beige tower PC has largely faded into history. Today, modern professionals frequently work from coffee shops, home offices, or coworking spaces. For all the benefits this has brought, this flexibility also poses a significant challenge for business leaders and IT managers: how do you provide a secure, high-performance desktop experience to a workforce that’s scattered across the country?

At Sota, we’ve spent more than three decades helping organisations navigate these shifts in the working landscape. One of the most transformative solutions we’ve encountered (and one we frequently implement) is Azure Virtual Desktop. Microsoft’s cloud solution bridges the gap between strict corporate security and employee mobility—and understanding why starts with looking at the concept of virtualisation itself.

What is a virtual desktop?

In a traditional setup, your ‘desktop’ (including your operating system, your files, and your applications) lives physically on the hard drive of the laptop or PC sitting in front of you. This is known as local computing. Long story short, if you leave that laptop at the office, you cannot access your desktop from home. If the laptop is stolen, the data on it is potentially also at risk—as is the data of any service you’re still logged into.

A virtual desktop works by uncoupling the desktop environment from your physical hardware. Instead of running on the device in front of you, the desktop runs on a powerful server located elsewhere. When you log in to a virtual desktop, your mouse clicks and keystrokes are sent over the internet to that server, and the server sends back a visual stream of the desktop.

It’s not dissimilar to how a streaming service like Netflix works. Instead of downloading the movie to your TV, you’re seeing a version of it that’s being played on a remote server. With a virtual desktop, you are viewing a stream of your Windows environment. The advantage of this is that regardless of the device you use to access it—whether that’s an old laptop, a tablet, or even a smartphone—the heavy lifting is being done by the remote server, meaning that any device capable of streaming data is capable of running software.

What is Azure Virtual Desktop?

Azure Virtual Desktop (AVD) is Microsoft’s cloud-based desktop and application virtualisation service. While virtual desktops have existed for a long time, they were historically expensive and complex for businesses to manage because they required the company to own and maintain their own high-end servers. AVD was among the first concerted attempts to host those virtual desktops on a cloud platform, and remains a market leader today.

For your business, this means not having to buy, cool, or power the servers that run your virtual desktops. With Microsoft handling the underlying infrastructure, you simply manage the desktop experience for your staff, scaling your investment according to your requirements. As a Microsoft service, AVD is also the only virtual desktop provider that provides a multi-session Windows 11 or Windows 10 experience, allowing multiple employees to use the same virtual machine simultaneously. This ability to share resources can significantly reduce your costs, without sacrificing that familiar Windows feel for staff.

At Sota, we often describe AVD as a managed gateway to a more agile business model. Because it integrates natively with Microsoft 365 and Teams, it provides a seamless experience for users already embedded in that ecosystem. Staff can log in and see their familiar icons, their emails synced to Outlook, and their OneDrive files where they left them. Simply put, if your organisation uses Windows, Azure Virtual Desktop is the most seamless and familiar option for desktop virtualisation.

How does Azure Virtual Desktop work?

A good way to understand how AVD functions in a real-world scenario is to picture it as three layers: the client device, the Azure cloud, and the management layer.

The process begins with the user’s device (typically your PC). You open the Azure Virtual Desktop app or a web browser, and enter your corporate credentials, usually protected by Multi-Factor Authentication (MFA) such as an authenticator. Once authenticated, the device establishes a secure connection to the Microsoft Azure data centre.

This is the Azure cloud. Here, Microsoft has set up a ‘host pool’, a collection of virtual machines configured with your company’s specific apps and security settings. When the user logs in, the service assigns them a virtual desktop from this pool. Because the data and the applications are sitting in the same data centre as the virtual machine, the performance is often much faster than it would be on a local laptop, especially when handling large files or complex databases.

The management layer is where Sota’s expertise often comes into play. While Microsoft manages the hardware in the cloud, you still need someone to manage the desktops. This includes jobs like keeping the operating systems up-to-date, managing security software, and scaling the host pools as your need for desktops grows. If you have 100 staff starting work at 9:00 AM, you need enough virtual machines active to handle that load. Conversely, if only five people are working on a Sunday evening, you want the system to automatically turn off the unused machines to save on costs.

This pay-as-you-go model is one of the most technical but beneficial aspects of how AVD works. Rather than paying for a server to sit idle at night, you only pay for the minutes of computing time your staff actually use. Provided that it’s architected correctly from the start, it’s an incredibly efficient way to manage a corporate IT estate.

Use cases for Azure Virtual Desktop

While almost any business can benefit from the flexibility of AVD, there are several scenarios where our clients typically see the most profound benefits of AVD, and Azure more generally:

1. Security and compliance

If you’re in a highly regulated sector like finance, law, or healthcare, data security is likely to be very high on your list of priorities. Traditionally, that has been a reason to maintain your own servers to ensure you know exactly where your data is, particularly with the advent of GDPR.

With AVD, no corporate data ever actually leaves the secure Azure data centre, which in a managed environment can be guaranteed as operating in a GDPR compliant location. Since the desktop only exists in the cloud, and access can be revoked instantly by the IT team, there’s no anxiety about losing a laptop on a bus or train. This has the added benefit of making it much easier to meet strict compliance standards like Cyber Essentials Plus, a common requirement for public sector contracts in particular.

2. Remote and hybrid workforces

Many companies now operate a Bring Your Own Device (BYOD) policy, or have a mix of home and office workers combining work-issued hardware with their own devices. Unfortunately, managing this fleet of different personal laptops and phones is a security nightmare, with every one being a potential vector for malware or data loss.

AVD solves this by providing a consistent, secure bubble for sensitive data that runs on any device. An employee can use their personal MacBook at home to log into a fully managed, secure Windows 11 corporate desktop, keeping their personal life and work life completely separate on the same machine.

3. Temporary staff and contractors

When you hire contractors or seasonal staff, the traditional process of ordering, configuring, and shipping a laptop can take weeks, and end up being more expensive the shorter the notice is. With AVD, you can provision a new desktop in minutes.

By granting the contractor access to your host pool, they can start working immediately from their own equipment without introducing any security risk. When the contract ends, you simply revoke access, and the virtual desktop is instantly decommissioned, with no hardware to chase down and recover.

4. High-performance engineering and design

Historically, architects and engineers required expensive workstation PCs with high-end graphics cards to run software like AutoCAD or Revit. These machines were heavy and difficult to move, and the recent demand for GPUs to train and run AI models has seen prices skyrocket.

With AVD, you can provision GPU-enabled virtual machines in the cloud, taking advantage of Microsoft’s ability to secure hardware discounts at scale. An engineer can then run these power and resource-hungry applications from a lightweight laptop or tablet, with the heavy graphical processing being handled by the massive resources of Azure’s data centres.

A view to better virtualisation

Implementing Azure Virtual Desktop is a great way to significantly reduce your hardware costs and massively increase your organisational agility in one fell stroke. While the technology is powerful, however, the setup requires a professional touch to ensure it is as secure and cost-effective as possible. Without the right auto-scaling rules or security configurations, cloud costs can escalate, and performance can lag.

At Sota, we’ve spent over thirty-five years helping businesses bridge the gap between their current reality and their future potential. We provide the consultative partnership needed to ensure AVD works for your specific people and processes. By hosting your virtual desktops in the global Azure cloud and having them managed by a local, experienced UK partner, you get the best of both worlds: world-class infrastructure and personal, responsive support.

If you’re looking to move away from the cycle of expensive hardware refreshes and toward a more resilient, mobile future, Azure Virtual Desktop is the path forward. Visit our Azure page to learn more, or get in touch with us today.
