EKS vs Self-Managed Kubernetes: 2026 Decision

EKS removes 80% of control-plane operational burden. The cases where the remaining 20% justifies self-managed.

When EKS wins

Most teams. Control-plane is a commodity; operating it is undifferentiated heavy lifting.

Cost is real ($72/month per cluster) but small relative to engineering time saved.

When self-managed wins

Custom control-plane requirements. Specific scheduler plugins, custom admission controllers.

Cost-sensitive at extreme scale. The $72/month becomes meaningful at 1000+ clusters.

Hybrid

Some teams: EKS for production; self-managed for niche internal use cases.

Operational complexity adds up; only hybrid if you have a strong reason.
