Amazon ECS Service Discovery | Amazon Web Services
Amazon Elastic Container Service (Amazon ECS) now includes integrated service discovery. This makes it possible for an ECS service to automatically register itself with a predictable and friendly DNS name in Amazon Route 53. As your services scale up or down in response to load or container health, the Route 53 hosted zone is kept up to date, allowing other services to lookup where they need to make connections based on the state of each service.
