http://aws.amazon.com/solutions/case-studies/coursera-ecs/ “ Amazon ECS enabled Coursera to focus on releasing new software rather than spending time managing clusters.” Frank Chen Software Engineer •  Docker containers on Amazon EC2 Container Service (ECS) enabled Coursera to easily move to a microservices -based architecture. •  Each job is created as a container and Amazon ECS schedules the container across the Amazon EC2 instance cluster. •  Amazon ECS handles all the cluster management and container orchestration, and containers provide the necessary resource isolation.
