Introduction
In this lesson, we will learn about two essential Microsoft Azure services. The App Service plan and the App Service.
Azure App Service is a PaaSPlatform as a service Microsoft Azure resource that hosts web applications and RESTful APIs developed in several programming languages, including .NET, .NET Core, Java, and PHP.
The Azure App Service plan is the underlying compute environment that Azure App Service uses. All Azure App Services with the same plan share the same compute resources. A single Azure App Service plan can host multiple Azure App services.
Behind the scenes, Azure App service plans run on Azure VMs. However, we do not need to bother about those VMs as Microsoft manages them on our behalf, as we use Azure App Service as a PaaS service.
The figure below illustrates the relationship between Azure App Service and Azure App Service Plan.
