You are designing a high-availability solution for a multi-tier containerized app that will be hosted in a multi-node Azure Kubernetes Service (AKS) cluster. The cluster nodes will be distributed across three availability zones. Each tier will contain three pods.

You need to ensure that active pods of the app are distributed across all the availability zones.

Which AKS feature should you use?
