-An App Service plan defines a set of compute resources for an app to run. These compute resources are analogous to the [_server farm_](https://wikipedia.org/wiki/Server_farm) in conventional hosting. One or more function apps can be configured to run on the same computing resources (App Service plan) as other App Service apps, such as web apps. These plans include Basic, Standard, Premium, and Isolated SKUs. For details about how the App Service plan works, see the [Azure App Service plans in-depth overview](../app-service/overview-hosting-plans.md).
