If you're abstracting away most of the complexity of k8s, why not just go use ECS and spend nothing on the cluster? You will probably have to do some rewriting

If you're abstracting away most of the complexity of k8s, why not just go use ECS and spend nothing on the cluster? You will probably have to do some rewriting of your deployment scripts when you move off of EKS anyway (just like when you move off of ECS), so you might as well use ECS and save the $90/m (and it's generally easier to use).
