In the previous section, we created a sample HTTP function. In a real-world use case, queues are often used to pass messages between different components of an application. A function can be triggered based on messages in a queue to then perform additional processing on these messages.

In this section, we'll create a function that is integrated with storage queues to consume events. We will also configure KEDA to allow scaling to/from 0 Pods in case of low traffic.

We still start by creating a queue in Azure.
