Plan upgrades inside the 14-month standard window to avoid paying for extended support.

A Kubernetes minor version released on EKS gets about 14 months of standard support and then 12 months of extended support at a higher cluster price.

Cadence beats heroics

Kubernetes ships roughly three minors a year. Upgrading one or two minors every few months is routine; skipping five is a project.

Cost of waiting

Standard support costs a fraction of extended per cluster-hour. For many clusters the premium is real money. Check the current EKS pricing page.

Skew rules apply

Upgrade the control plane one minor at a time. Nodes may lag the control plane within the supported skew, but never lead it.

EKS versions have a clock: standard, then extended support

EKS supports each Kubernetes minor version for a fixed period. A version is in standard support for roughly the first 14 months after it becomes available on EKS, then enters extended support for another 12 months, during which you pay a higher per-cluster hourly price and AWS continues to provide patches. After that, clusters are automatically upgraded. Exact dates are published in the EKS version calendar, and pricing on the EKS pricing page: both change, so check them.

Why it matters for operations: the support clock turns upgrades into a scheduled, recurring activity rather than an occasional emergency. Teams that upgrade every cluster once or twice a year, and keep at most a minor or two behind, rarely pay for extended support and never face a forced upgrade.

Remember the Kubernetes rules that apply regardless of provider. Upgrade the control plane one minor version at a time; nodes can be a limited number of minors behind the control plane but never ahead; and deprecated APIs removed in the new version will break manifests that still use them. Module 6 builds the full upgrade runbook.

Reveal the three phases with the right arrow. The honest summary for a platform lead: budget for a quarterly upgrade rhythm per cluster, and treat extended support as a safety valve for a missed window, not a plan.
