During this talk we will focus on scale-down logic of Cluster Autoscaler. You will learn what are the criteria that Cluster Autoscaler uses to decide whether a node can be scaled down, how this process can be customized and how you can help autoscaler scale-down your cluster more effectively. You will also have a chance to participate in Q&A session with SIG-Autoscaling members specializing in all our projects: Cluster Autoscaler, Horizontal Pod Autoscaler, Vertical Pod Autoscaler, and ask questions about best practices, common pitfalls and configuration issues.
