Amazon EKS adds extended support to simplify Kubernetes upgrades

Amazon Elastic Kubernetes Service (EKS) has introduced an Extended Support offering, generally available in April 2024, that lengthens the availability of each Kubernetes version to 26 months. The change aims to reduce the operational friction of upgrading control planes, allowing regulated industries, large enterprises and ISVs to schedule upgrades on their own timelines without being forced into rushed migrations.

Best‑practice guidance for Kubernetes upgrades emphasizes thorough preparation: reviewing release notes for breaking changes, auditing deprecated APIs, and using PodDisruptionBudgets. Upgrades should be performed incrementally—control‑plane components first, then nodes in small batches—while monitoring key metrics such as API‑server latency and pod health. Rollbacks are difficult, so the recommended approach is to pause further upgrades until each batch is confirmed healthy.
