Azure Kubernetes Service (AKS) cluster autoscaler is in preview
Updated: March 19, 2019
AKS cluster autoscaling is now available in preview. This service enables you to scale more efficiently and run your applications without downtime. Based on the Kubernetes cluster autoscaler, AKS autoscaling automatically adds new instances to the Azure virtual machine scale set when more capacity is required and removes them when no longer needed. Combine it with the horizontal pod autoscaler to precisely tune the scaling behavior of your environment to match your workloads.
