Windows Server app modernization with containers

Windows Server as a container host simply runs a container. When you have a complex app with multiple containers, you need a container orchestrator, such as Kubernetes. That's what AKS is - a managed Kubernetes service on Azure where you don't have to manage the Kubernetes infra itself. As for containerizing, two things: First, Windows containers don't support apps with a GUI. We have more details here: https://learn.microsoft.com/en-us/virtualization/windowscontainers/quick-start/lift-shift-to-containers. Second, for containerization, you can use something like Azure Migrate or any other solution that Fady mentioned.
