 [Azure Container Apps automatically scales HTTP traffic to zero.](./scale-app.md) However, to scale non-HTTP traffic (like [Dapr](https://docs.dapr.io/) pub/sub and bindings), you can use [KEDA scalers](https://keda.sh/) to scale your application and its Dapr sidecar up and down, based on the number of pending inbound events and messages. 
 
 This guide demonstrates how to configure the scale rules of a Dapr pub/sub application with a KEDA messaging scaler. For context, refer to the corresponding sample pub/sub applications:
