Vertical Pod Autoscaler

Jan 1, 0001

Definition

Vertical Pod Autoscaler (VPA) is a Kubernetes component that automatically adjusts the CPU and memory resource requests and limits for containers in a pod. It helps ensure that applications have the necessary resources to run efficiently while minimizing waste. VPA can operate in three modes: “Off” for recommendations only, “Auto” for automatic updates, and “Recreate” for updating pods by recreating them.
