Explanation:
About the cluster autoscaler.
AKS clusters can scale in one of two ways:
The cluster autoscaler watches for pods that can’t be scheduled on nodes because of resource constraints. The cluster then automatically increases the number of nodes.
The horizontal pod autoscaler uses the Metrics Server in a Kubernetes cluster to monitor the resource demand of pods.
