Three-column shared-responsibility comparison of managed Kubernetes offerings: GKE Autopilot, where Google manages both the control plane and the node infrastructure and customers own only pod-level resource requests (pay-per-pod); Azure AKS, where Azure manages only the control plane while customers size, patch, and scale their own VM Scale Set node pools (pay-per-node); and AWS EKS, where AWS manages only the control plane while customers own EC2 worker nodes, AMIs, and Auto Scaling groups — the largest customer-owned footprint of the three (pay-per-node).
