  • hosting plans are
    • consumption plan : azure provisions all the necessary resources for running function and we pay as function is running
    • app service plan : just like web app. we can use the same plan with no additional costs
  • runtime stack
    • node js
    • .net core

  • service bus queue
  • service bus topic
Consumption Plan (Pay for what used)App Service Plan (predictable monthly cost)Premium Plan
Basic or higher tierimproved performance
Scaling is integrated in serviceScaling must be configuredVnet support
Pay for number of execution
Pay for CPU time & RAM
