summary
Overview of Kubernetes autoscaling fundamentals and concrete changes: Horizontal Pod Autoscaler computes independent recommendations per metric and picks the maximum, with configurable scale stabilization (default 5m), rate limits and min/max policies; v2 moves those behaviors into a HPA v2 stable API. Vertical Pod Autoscaler uses a recommender, updater (rolling single-pod deletes), and admission controller; new support for VPA multiple recommenders via a discriminator field. Cluster Autoscaler reacts to unschedulable pods, taints and drains empty nodes, and selects node pools by size.
