Amazon Elastic Container Service (Amazon ECS)

• ECS is capable of running in EC2 mode or Fargate mode.

• EC2 mode deploys EC2 instances into your AWS account which can be used to deploy tasks and services.

• With EC2 mode you pay for the EC2 instances regardless of container usage

• Fargate mode uses shared AWS infrastructure, and ENI's which are injected into your VPC

• You pay only for container resources used while they are running.
