Choosing the right app model
The Azure stack offers multiple ways to host web applications, varying from simple Infrastructure as a Service (IaaS) offerings such as Virtual Machines (VMs) to completely managed PaaS hosting services such as App Service. Because of the platform-agnostic nature of .NET Core and ASP.NET Core, even Linux containers and container orchestration services such as Kubernetes are available options.
