HPA, VPA, or KEDA: Which Kubernetes Autoscaler Actually Saves Money?
Kubernetes offers three autoscalers: HPA adjusts pod count, VPA adjusts pod size, and KEDA scales to zero. HPA saves on variable traffic but keeps one pod always running; VPA reduces over-provisioning waste; KEDA eliminates idle costs by scaling to zero. Most mature setups combine all three for maximum savings.
