App Service announces the general availability of Windows Container support

Published date: September 22, 2020

On October 1st, App Service support for Windows Containers will be available in more regions with full production SLAs and support for regional network integration, Private Link, and Managed Server Identity.

You will be able to deploy web applications, along with any dependencies, in a Windows Container on Azure App Service, enabling a broader sets of applications to take advantage of a fully managed hosting environment:

  • Applications with dependencies: Deploying your application in a Windows Container enables you to bring along dependencies such as custom fonts, cultures and GAC deployed assemblies.
  • Lift and shift to PaaS: If you're interested in migrating .NET Framework and .NET Core applications to Azure, you can containerize and go straight to a PaaS service to get the many productivity benefits from App Service.
  • Relaxed security restrictions: When deploying a containerized application, the Windows Container is an isolation and security boundary. As a result, calls to libraries that would normally be blocked by the Azure App Service will instead succeed when running inside of a Windows Container. For example, many PDF generation libraries make calls to graphics device interface (GDI) APIs. With Windows Containers, these calls will succeed.
  • Third-party application migration: You might have business critical applications developed by third parties with which you no longer hold a relationship. Containerizing these applications unblocks the opportunity to migrate to Azure App Service
