Deployment models
VMware Horizon offers maximum deployment flexibility. You can run it entirely on-premises, in any public cloud, or in a hybrid configuration. This flexibility suits organisations with specific data residency requirements or existing infrastructure investments. The trade-off is complexity; you’re responsible for the underlying infrastructure, whether that’s managing ESXi hosts or cloud instances.
Azure Virtual Desktop is inherently cloud-based, running exclusively on Azure. While this might seem limiting, it eliminates infrastructure management overhead. You don’t worry about host servers, load balancers, or connection brokers. Microsoft handles the control plane, leaving you to focus on desktop images and user management. For organisations comfortable with cloud-first approaches, this simplification is liberating.
Cost considerations
VMware Horizon follows a traditional enterprise licensing model with per-user or per-device options. The initial investment can be a big one, especially when you add in infrastructure, licensing, and ongoing maintenance. Recent changes under Omnissa ownership have maintained similar pricing structures, though without the broader VMware bundle complications that emerged post-Broadcom acquisition.
Azure Virtual Desktop operates on a consumption model. You pay for the Azure compute, storage, and networking resources that you use, plus Windows licensing (often covered by existing Microsoft 365 subscriptions). This model can deliver decent savings for variable workloads but it does take careful monitoring to avoid unexpected costs. The lack of upfront infrastructure investment makes AVD a good shout for pilot projects or seasonal workloads.
Performance
VMware Horizon delivers consistent, predictable performance, particularly when deployed on-premises or with dedicated cloud resources. The Blast Extreme display protocol adapts well to varying network conditions (giving you a super smooth display experience), and local infrastructure deployment can minimise latency. Performance tuning options are extensive, allowing fine-grained optimisation for specific use cases.
Azure Virtual Desktop performance depends heavily on Azure region selection and network connectivity to Azure. Microsoft’s global infrastructure generally delivers excellent performance, but you’re sharing resources in a multi-tenant environment. The RDP-based protocol, while it’s been improved with recent updates, might not match Blast Extreme’s efficiency in challenging network conditions. However, AVD’s Teams optimisation often outperforms VMware Horizon in Microsoft-centric workflows.
Security features
VMware Horizon has strong security controls, including multi-factor authentication, smart card support, and USB redirection policies. Network isolation through NSX integration enables micro-segmentation, while Workspace ONE integration adds device trust and conditional access capabilities. Security will remain largely under your control and you’ll have to configure many things yourself.
Azure Virtual Desktop benefits from Azure’s security infrastructure. You get to enjoy things like conditional access policies, Azure Security Center integration, and automatic threat detection. Multi-factor authentication through Azure AD / Entra ID is straightforward to get up and running. Microsoft handles infrastructure security patches automatically, reducing the attack surface that makes you vulnerable. The challenge comes in understanding the shared responsibility model and making sure your configurations align with security requirements.
Scalability
VMware Horizon scales predictably but does take some planning. Adding capacity means provisioning additional hosts (whether that’s physical or virtual) and making sure your supporting infrastructure can handle the load. Instant clones help with rapid desktop provisioning, but ultimately, capacity depends on how much you’ve invested into your infrastructure.
Azure Virtual Desktop offers near-infinite scalability within Azure’s capacity limits. Auto-scaling capabilities can automatically adjust capacity based on demand, spinning up additional session hosts during peak times and shutting them down when not needed. This elasticity is definitely valuable for firms with variable or unpredictable workloads.
Management and simplicity
VMware Horizon takes some serious expertise to deploy and manage it effectively. The management console is comprehensive but complex, with lots of configuration options across multiple components. While this gives you a precise level of control, it also means a steeper learning curve and higher operational overhead.
Azure Virtual Desktop simplifies management through Azure Portal integration and PowerShell automation. The managed service approach means fewer components to configure and maintain. That said, you’ll need familiarity with Azure concepts like resource groups, virtual networks, and Azure AD. For teams already managing Azure resources, AVD feels familiar; for those new to Azure, there’s still a learning curve.
