Azure Container Apps: KEDA and Dapr Managed

Kubernetes is hard. Azure Container Apps (ACA) gives you K8s + KEDA + Dapr without the control plane tax.

Scale to Zero

ACA can scale your HTTP service to 0 replicas when no requests are coming in. Even better, it uses KEDA scalers.

scale:
  minReplicas: 0
  maxReplicas: 10
  rules:
  - name: azure-queue
    custom:
      type: azure-queue
      metadata:
        queueName: orders
        queueLength: '10'

This configuration automatically scales your container based on the depth of an Azure Storage Queue. You write zero code for this.
