Scaling out, which is sometimes called horizontal scaling, means adding new instances of the application. The Horizontal Pod Autoscaler, or HPA, monitors the resource demand and automatically scales the number of pods. HPA is updated every 60 seconds. When changes are required, the number of replicas is increased or decreased accordingly. When you configure the HPA, you define the minimum and maximum number of replicas per deployment. Cluster autoscaler provides AKS with horizontal scaling for a cluster nodes. The cluster autoscaler checks the metrics API server every 10 seconds for any required changes in node count. If the cluster autoscaler determines that a change is required, the number of nodes in your AKS cluster is…
