Azure Functions App Service Plan

The Azure Function, App Service plan, defines a set of computing resources for the Azure Function App or other web apps. Multiple Azure Function App also can run on the same App Service plan.

While creating the App service plan, we choose the region, and internally, a set of computing resources is created for that plan in that particular region.

Each App Service Plan defines the region, the number of Virtual machine instances, the size of the VM, which could be Small, Medium, or Large, and the pricing tier, which could be Basic, shared, free, premium, etc.

When To Choose App Service Plan?

Choose the App service plan in case of a few key scenarios like the one below

  1. In case you have any existing Virtual machines running other App Service instances.
  2. You can also choose the App Service Plan in case you want to provide any custom image on which you want to run your Azure Functions.

Azure Function App service plan pricing

The pricing tier of an App Service Plan is purely based on the App service features you are getting and the price you are paying for the same.

Below are a few pricing tiers of the App service plan

  • Free and Shared Compute: As per these tiers, You need to run an Azure Function App on the same virtual machine where the other App Service Apps are running.
  • Dedicated Compute: In the case of standard, Basic, and Premium tiers, the app runs on the dedicated Azure virtual machines. Only if the App belongs to the same App Service Plan can share the same compute resources.
  • Isolated: In the case of the Isolated tier, the Azure VMs run on the dedicated Azure Virtual Network.

When you have created an app in the App service, it comes under the same App Service Plan. When the app starts running, it runs on all the virtual machine instances configured under the same App Service Plan.
