EKS Kubernetes 1.36 is available with user namespaces GA and mutating admission policies. Since July 2026 you can roll back an in-place control-plane upgrade within 7 days at no extra charge — but only N→N-1, and Fargate or strict PDBs can block you.
On July 31, 2026 AWS shipped CloudWatch managed Prometheus collectors. For the AWS Example 22 shape (100 hosts x 50 metrics @ 60s), OTLP ingestion is $54/mo vs $1,500 classic custom metrics if you do not double-ingest.
EKS control planes are $73/month per cluster. Stay on a Kubernetes version beyond its 14-month standard support and Extended Support bills $0.60/cluster-hour — $438/month per cluster, a 6× multiplier vs standard. EKS Auto Mode adds a ~12% markup over standard EC2 + EBS for managed compute simplicity. The compute side (Karpenter, Spot, Graviton) is where most of the bill lives.
