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. | An Amazon ECS cluster is a regional, logical grouping of [[#Task|tasks]] or [[#Service|services]].

Overview
Amazon Elastic Container Service (ECS) allows deploying Docker containers on a scalable cluster. Docker images to be deployed typically come from Amazon ECR.
Task
Task Definition
The task definition is the configuration of the application. It specifies the Docker image, how many containers to use for this task and the resource allocation for each container.
Cluster
An Amazon ECS cluster is a regional, logical grouping of tasks or 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.
