Let's understand the different components or resources that are used while creating Azure Functions.
The following image describes the Functions in Azure in different pricing plans:
A function app is a collection of one or more functions that are managed together. All the functions in a Function App share the same pricing plan and it can be a consumption plan or an App Service plan. When we utilize Visual Studio Team Services for Continuous Integration and Continuous Delivery using build and release definitions, then the Function app is also shared. The way we manage different resources in Azure with the Azure Resource Group is similar to how we can manage multiple functions with the Function App.
