EC2), AWS manages the compute for you; I'm taking a look at AWS ECS Fargate to see what it takes to deploy a Docker container. Depending on your usage, I suggest you use an EC2 instance, use CodeBuild or build an operator that is able to talk with the api to span containers. However, building containers using Docker in environments like Amazon ECS and Amazon EKS requires running Docker in Docker, which has profound implications. Im a passionate engineer based in London.
