Azure function app scaling is a feature that allows you to automatically scale your function app based on the number of events. This feature is useful when you have a function app that is triggered by a large number of events. For example, if you have a function app that is triggered by a large number of events, you can use this feature to automatically scale your function app based on the number of events.

Azure Load Testing service in Azure offers a way to test the performance of your Azure function app. You can use this service to test the performance of your Azure function app by running a load test against it. The load test can simulate a large number of requests to any URL. This functionality makes it the best candidate to test the applications under load and analyze the performance of the application.

In this hands-on lab, you will create an Azure Load Testing service and run a load test against an Azure function app. You will analyze the Azure function scaling behavior and the impact of the load test on the Azure function app.
