Desktop as a Service (DaaS) on Azure is a game-changer for businesses looking to streamline their desktop infrastructure. By leveraging Azure's robust cloud platform, you can deploy virtual desktops in a matter of minutes, eliminating the need for physical hardware and maintenance.
Azure's DaaS offering is built on top of Windows Virtual Desktop (WVD), which provides a scalable and secure way to deliver desktops to users. With WVD, you can create a virtual desktop environment that's identical to your on-premises setup, but with the added benefits of cloud scalability and flexibility.
Implementing DaaS on Azure requires a solid understanding of the underlying infrastructure and configuration options. To get started, you'll need to set up a virtual network, create a WVD host pool, and configure your desktop images.
What is Desktop as a Service (DaaS)?
Desktop as a Service (DaaS) is a cloud-based solution that allows users to access virtualized applications and desktops from any device, regardless of their location. This is made possible by cloud-hosted virtualized applications and desktops.
Azure DaaS is a high-performance, secure platform that simplifies the scaling of virtual desktops, applications, and data. It offers a predictable, subscription-based payment model.
The Azure DaaS model is implemented using Microsoft's Virtual Desktop Infrastructure (VDI) platform. This platform enables enterprises to run traditional desktop workloads on centralized virtual machines.
Azure DaaS provides comprehensive managed services on various aspects of desktop virtualization. These include:
- Brokering
- Maintenance
- Network
- Storage
- Licensing
- Hosting
Azure Virtual Desktop (VDI) offers DaaS capabilities to deliver Windows-based desktops and applications securely over the internet. This eliminates the need for onsite servers or physical computing devices.
Azure VDI allows organizations to deploy their own customized desktop images with preconfigured settings or choose from a range of ready-to-use templates. These include standard configurations like Windows Server 2016 Standard and Windows 10 (Pro, Enterprise, or Education).
Benefits of VDI
With Azure Virtual Desktop, you can access virtualized Windows 11 and Windows 10 desktops and apps with the security and reliability of Azure.
Azure Virtual Desktop allows users to move data between multiple deployment platforms while supporting a bring-your-own-device (BYOD) working model, giving them the flexibility to work from anywhere.
Simplified desktop management is a key benefit of VDI, as it outsources the deployment, configuration, and management of desktop applications, reducing administrative overhead.
The flexible scalability of Azure VDI deployments also simplifies IT administration functions, making it easier to manage and maintain desktop infrastructure.
Azure VDI services eliminate the cost of procuring physical hardware, helping save expenses on resource upskilling towards management of desktop infrastructure.
Here are some of the key benefits of VDI:
- Enables remote work
- Simplified desktop management

Technical Architecture and Infrastructure
Enterprise Cloud PCs run in a Microsoft-managed Azure subscription, where admins don't have direct access to the VM and incur egress transfer costs.
Azure AD DS is not supported for Enterprise Cloud PCs, and cloud-only Azure AD join is also not supported. However, Azure AD Hybrid Join is required.
To set up Enterprise Cloud PCs, you'll need an Azure subscription with a vNet that can access Active Directory domain controllers. You'll also need Azure AD Connect configured and running within Active Directory with AAD Hybrid Join enabled.
Here's a summary of the Enterprise Cloud PC pre-requisites:
- Azure subscription with vNet
- Azure vNet can access Active Directory domain controller (i.e. a PC can be joined to the domain)
- Azure AD Connect configured and running within Active Directory with AAD Hybrid Join enabled
- Intune enabled on Azure AD tenant
- Admin setting up the initial deployment must be an Owner of this Azure subscription
- Azure AD DS is NOT supported
Cloud Volumes ONTAP VDI
Cloud Volumes ONTAP VDI is a powerful combination that enables businesses to deliver virtual desktops with ease. Cloud Volumes ONTAP is a scalable and secure storage solution that can be used to host virtual desktops.
Azure's Virtualized Desktop Infrastructure (VDI) platform is used to implement a Desktop as a Service (DaaS) model, allowing end users to access virtualized desktops from anywhere. This is particularly useful in today's remote work landscape.
Cloud Volumes ONTAP can be used to store and manage virtual desktop images, making it easier to deploy and manage virtual desktops. This reduces the administrative burden on IT teams and makes it easier to scale up or down as needed.
Azure's VDI platform offers a range of benefits, including improved security, increased scalability, and reduced costs. By using Cloud Volumes ONTAP with Azure's VDI, businesses can create a highly available and secure virtual desktop environment.
Technical Architecture
Windows 365 and Azure Virtual Desktop both leverage Microsoft cloud technologies, but they have different transactional models. Windows 365 is built on top of existing AVD components and has a fixed price model, whereas AVD has a consumption-based model.
There are two versions of cloud PCs: Enterprise and Business. Enterprise cloud PCs are designed for organizations that have invested in Microsoft Endpoint Manager and are using it to manage their existing Windows 10 desktops.
The Enterprise cloud PC requires an Intune license for each user who is assigned a cloud PC M365 SKU. This license is necessary for management through the Microsoft Endpoint Manager portal.
Azure AD DS is not currently supported for Enterprise Cloud PCs, and cloud-only Azure AD join is also not supported.
To set up Enterprise Cloud PCs, you need to create an "on-premises network connection" in Microsoft Endpoint Manager, pointing at the vNet and providing AD credentials to join new VMs. This process may take a while to complete.
Here are the pre-requisites for Enterprise Cloud PC setup:
- Azure subscription with vNet
- Azure vNet can access Active Directory domain controller (i.e. a PC can be joined to the domain)
- Azure AD Connect configured and running within Active Directory with AAD Hybrid Join enabled
- Intune enabled on Azure AD tenant (each cloud PC user needs and Intune license assigned)
- Admin setting up the initial deployment must be an Owner of this Azure subscription
To entitle a user to a cloud PC, simply assign a cloud PC license to the user via the Windows 365 Admin portal. If the user is a member of a security group that's assigned to a cloud PC provisioning policy and the network connection is "healthy", a new cloud PC will start provisioning.

Efficient Deployments: Decoding Load Patterns
To achieve an efficient Azure Virtual Desktop deployment, you need to understand your specific load patterns. Different tasks and applications place varying demands on your virtual host.
A user working on word processing tasks exerts far less load on the system than someone operating a CAD-based virtual workstation. This means your virtual desktop should be robust enough to handle various graphic requirements, CPU needs, and memory demands.
Understanding the number of users and their usage patterns over time is also crucial. This information can help determine the appropriate number of hosts required and manage the number of virtual sessions each host can effectively handle.
Your virtual desktop should be able to handle tasks with varying demands on the system, such as graphic requirements, CPU needs, and memory demands. This requires careful planning and resource allocation to ensure smooth operation and optimal performance.
