Answer
HPA scales replicas; VPA adjusts resource requests and may restart Pods.
Quick Answer
HPA scales horizontally — adds or removes Pods based on current resource usage. VPA (Vertical Pod Autoscaler) scales vertically — adjusts the CPU and memory requests/limits of individual Pods based on actual usage. VPA is for right-sizing Pod resource requests over time. They address different problems and can conflict — typically don't use both for the same Deployment.
