Amazon EKS — Auto Scaling
Chapter 11 — Auto Scaling
Auto scaling on EKS operates at two levels: pod scaling (HPA/VPA) adjusts the number or size of pods, and node scaling (Cluster Autoscaler/Karpenter) adjusts the number of nodes.
What You’ll Learn
- Horizontal Pod Autoscaler (HPA) for scaling pod replicas
- Vertical Pod Autoscaler (VPA) for right-sizing resources
- Cluster Autoscaler for node scaling
- Karpenter for next-gen node provisioning
- KEDA for event-driven scaling
