Amazon EC2 Container Service (ECS) is a container management service that supports running and managing Docker containers on a cluster of Amazon EC2 instances. It provides built-in scheduling, cluster management, and orchestration capabilities to help run and scale containerized applications. ECS integrates with other AWS services like Elastic Load Balancing, Elastic Block Store, Virtual Private Cloud, and more. Users define tasks and services in task definitions that specify containers, resources, dependencies, and other configuration.

From Docker Hub
Mount volume from other container
Command to exec

15. Tasks
Good for short-lived
containers, e.g.
batch jobs

16. Services
Good for long-
running applications
and services

17. Service Scheduler
• Manage long-running applications and services
• Build-in
• What it does
• Load balacing
• Health management
• Scale-up and scale-down
• Update management
• Drain ELB
