• Licensing: Azure offers flexible licensing options for Windows VMs. For instance:

  • Azure Hybrid Benefit: If you have existing Windows Server licenses, you can bring them to Azure and reduce the cost of running Windows VMs.
  • Pay-as-you-go: Windows licenses can also be included in the hourly cost of the VM.

• Example Use Cases:

  • Hosting Windows-based enterprise applications (e.g., SharePoint, SQL Server).
  • Running custom Windows workloads that require specific configurations or legacy software.
  • Development and testing environments for Windows-based software.

2. Azure App Services for Windows

Azure App Service is a fully managed platform-as-a-service (PaaS) that allows you to build, deploy, and scale web applications on the Windows platform.

• Supported Technologies: Azure App Service supports .NET, Java, PHP, Node.js, and Python on Windows-based environments. If your web app is built using .NET Framework or ASP.NET, Azure App Service makes it easy to deploy and scale on a Windows-based hosting environment.

• Integrated Developer Tools: Azure provides integration with Visual Studio, GitHub, and Azure DevOps to facilitate continuous integration and deployment (CI/CD) pipelines for Windows-based web applications.

• Windows-Based Hosting: When creating a web app in Azure App Service, you can choose the operating system (Windows or Linux), but Windows is often preferred for .NET and ASP.NET applications.

• Features:

  • Automatic scaling and load balancing.
  • Built-in security, authentication, and authorization (integrates with Azure Active Directory).
  • SSL/TLS support for secure communication.

• Example Use Cases:

  • Hosting web applications built with ASP.NET.
  • Backend services for Windows-based applications.
  • RESTful APIs for Windows-based clients.

3. Azure Windows Virtual Desktop (WVD)

Windows Virtual Desktop (WVD) is a Desktop-as-a-Service (DaaS) offering from Microsoft, providing virtual desktop infrastructure (VDI) in the cloud.

• Virtualized Windows Desktop: WVD allows organizations to provide virtualized Windows desktops to users on any device, with Windows 10 or Windows 11 as the operating system.

• Multi-session Windows 10: WVD is unique in that it supports multi-session Windows 10, which allows multiple users to share the same virtual machine, reducing costs.

• Management and Integration: Windows Virtual Desktop integrates with Azure Active Directory for identity and access management, and provides management through Microsoft Endpoint Manager.

• Key Features:

  • Centralized management of desktops and apps.
  • Seamless integration with Microsoft 365 services (e.g., OneDrive, Teams).
  • Enterprise-level security and compliance, using tools like Azure Security Center and Azure AD.

• Example Use Cases:

  • Remote work environments for users who need access to Windows desktops from anywhere.
  • Secure virtual desktops for contractors or third-party collaborators.
  • Running legacy Windows applications in a virtualized environment.

4. Azure Active Directory (AAD) for Windows Integration

Azure Active Directory (AAD) is Microsoft's cloud-based identity and access management service, which integrates seamlessly with Windows systems.

• Azure AD Join: Azure AD allows for Windows 10/11 devices to be joined directly to Azure AD without the need for on-premises Active Directory (AD). This is particularly useful for remote and cloud-only environments.

• Hybrid Identity: Organizations that have both on-premises Windows Server Active Directory (AD) and Azure AD can integrate them with Azure AD Connect for a hybrid identity solution. This allows for a unified login experience across cloud and on-premises resources.

• Windows Autopilot: For Windows-based devices, Autopilot is a service that helps automate the provisioning of new Windows PCs, making it easier to deploy Windows devices in the enterprise.

• Single Sign-On (SSO): Azure AD enables SSO for Windows users, allowing them to seamlessly access cloud resources (e.g., Office 365) and on-premises apps.

• Conditional Access: You can enforce policies on Windows 10/11 devices to ensure secure access to cloud resources, based on factors like user identity, device health, and location.

5. Windows Server on Azure

Azure provides a range of solutions specifically designed for running Windows Server workloads in the cloud.

• Azure Virtual Machines for Windows Server: This allows businesses to run Windows Server in a highly flexible and scalable environment. You can choose the version of Windows Server you need (e.g., 2019, 2022) and configure the virtual machine according to the required resources.

• Azure Hybrid Benefit for Windows Server: If you already have Windows Server licenses with Software Assurance, Azure Hybrid Benefit enables you to use those licenses in the cloud, reducing costs.

• Windows Server Features in Azure:

  • Active Directory: You can use Azure Active Directory Domain Services (Azure AD DS) or integrate with on-premises AD to provide identity and authentication.
  • SQL Server: Host your Windows Server with SQL Server for enterprise-grade database workloads.
