I’ve been using ECS for a number of years now as I find that it is a lot simpler to understand that say Kubernetes. I belive Kubernetes is more suited to a team of teams that are developing microservices and you have the necessary staff in something akin to a platforms team to maintain the Kubernetes environment and associated services. Even with services like EKS there is still a more to maintain with Kubernetes. Read more
