For years, VMware Horizon filled a very specific role. It gave businesses a way to virtualize desktops, often hosted on-prem, with a level of control IT teams were comfortable with. It worked. It was familiar. And for many businesses, it became foundational.

Why Make the Move from Horizon?

This shift usually starts with cost or licensing uncertainty, but it rarely ends there.

1. On-prem infrastructure is becoming a tax on agility

   Horizon environments are often tightly coupled to on-prem hardware, storage, and networking. That means refresh cycles, capacity planning, and downtime risk all sit squarely with IT. In contrast, AVD and Windows 365 remove the infrastructure burden entirely. Scaling up or down becomes a policy decision, not a procurement project.

2.  The Microsoft ecosystem advantage is real

   For businesses already invested in Microsoft 365, Entra ID, Intune, and Defender, AVD and Windows 365 slot in naturally. Identity, security, device management, and access policies work together without complex integrations or parallel tooling. Horizon can integrate, but it doesn’t feel native in the same way.

3. Security models have evolved

   Modern desktop strategies assume devices will be lost, compromised, or unmanaged at times. Windows 365 and AVD are built with Zero Trust principles in mind: identity-based access, conditional access, data staying in the cloud, and rapid recovery when things go wrong. This is increasingly difficult to replicate cleanly in legacy, on-prem VDI designs.

4. User experience expectations have changed

   Users expect fast access, consistent performance, and the ability to work from anywhere, without jumping through hoops. Windows 365, in particular, reframes the desktop as a personal, persistent Cloud PC rather than a pooled resource. That subtle shift makes a big difference in day-to-day usability.

AVD vs Windows 365: Not One or the Other

One common misconception is that organizations must choose between AVD or Windows 365. In reality, many successful migrations use both.

The goal is to design a desktop strategy that matches different user needs with the right delivery model.

How to Prepare for the Move

This is where many migrations succeed or stumble.

1. Start with user personas

Before touching architecture, map how people actually work. Who needs a persistent desktop? Who can share pooled resources? Who needs high performance, and who just needs reliable access? Horizon environments often treat users uniformly; cloud desktops work best when tailored.

2. Clean up identity and access first

AVD and Windows 365 are identity-driven. If Entra ID, Conditional Access, MFA, and device compliance policies aren’t solid, those cracks will show quickly. Getting identity right upfront reduces friction later and improves security from day one.

3. Rethink application delivery

This is a chance to modernize. Move away from image sprawl and manual app installs toward Intune, MSIX, and policy-based deployment. Fewer images, more automation, and faster change cycles.

4. Plan for coexistence, not big-bang cutovers

Most businesses don’t move everything at once. Running Horizon alongside AVD or Windows 365 for a period allows you to validate performance, user experience, and cost models without disrupting the business.

5. Build resilience into the design

One of the biggest advantages of Windows 365 is how well it supports business continuity. Features like Windows 365 Reserve Cloud PC allow users to stay productive during device loss or security incidents. This is where cloud desktops stop being “VDI” and start being an operational safety net.

Conclusion

Businesses that succeed don’t just migrate workloads. They rethink how desktops are delivered, secured, and recovered, with the assumption that disruption will happen, and productivity shouldn’t stop when it does.

That’s the opportunity AVD and Windows 365 unlock when done right.
