An Amazon ECS cluster is a regional grouping of one or more container instances (services) on which you can run task requests. Clusters may contain more than one Amazon EC2 instance type.
An Amazon ECS cluster is a regional, logical grouping of [[#Task|tasks]] or [[#Service|services]]. If the tasks or services in question use the EC2 launch type, the cluster is also a grouping of container instances. A default cluster is always available, but multiple clusters can be created in an account to keep your resources separate. A cluster cannot span more than one region.
