Most likely yes. They've seen the writing on the wall, that K8s has won. It will probably just be a slow deprecation like they did with Simple DB.
EKS is the optimized-for-AWS version of Kubernetes.
There’s also AWS Fargate, which is a more managed version of ECS.
(Disclaimer: I work for Amazon, but don't have inside knowledge of the AWS Containers Organization's plans.)
How can EKS be better for AWS customers?
EKS is just what everyone uses plugged into AWS.
Can't understand how this should be better.
