Amazon ECS Clusters

An Amazon ECS cluster is a logical grouping of tasks or services. When you first use Amazon ECS, a default cluster is created for you, but you can create multiple clusters in an account to keep your resources separate.

The following are general concepts about Amazon ECS clusters.

  • Clusters are Region-specific.

  • Clusters can contain tasks using both the Fargate and EC2 launch types. For more information about launch types, see Amazon ECS Launch Types.

  • You can create custom IAM policies for your clusters to allow or restrict user access to specific clusters. For more information, see the Clusters section in Amazon ECS IAM Policy Examples.

  • Clusters with Fargate tasks can be scaled using Service Auto Scaling. For more information, see Service Auto Scaling.
