While Extended Support covers all of the Kubernetes specific components from AWS, it will only provide support for AWS-published Amazon EKS optimized AMIs for Amazon Linux, Bottlerocket, and Windows at all times. This means, you will potentially have newer components (such as OS or kernel) on your Amazon EKS optimized AMI while using Extended Support. For example, once Amazon Linux 2 reaches the end of its lifecycle in 2025, the Amazon EKS optimized Amazon Linux AMIs will be built using a newer Amazon Linux OS. Amazon EKS will announce and document important support lifecycle discrepancies such as this for each Kubernetes version.
