ECS Application

An ECS application is a collection of deployment groups and revisions. The deployments use the ECS compute platform.

Working with Deployment Groups in CodeDeploy

Deployment Group Types

ECS Deployment Group

An ECS Deployment Group specifies the ECS service with the containerized application to deploy as a task set, a production and optional test listener used to serve traffic to the deployed application, when to reroute traffic and terminate the deployed application's original task set, and optional trigger, alarm, and rollback settings.

Target Group

In the context of a deployment group, a load balancer target groups routes traffic during your deployment. CodeDeploy binds one target group to the Amazon ECS service's original task set and the other to its replacement task set. For more details, see:

Deployment

Deployment Types

ECS Deployment

An ECS deployment is a process that deploys an updated version of an ECS containerized application as a new, replacement task set. CodeDeploy reroutes production traffic from the task set with the original version to the new replacement task set with the updated version. When the deployment completes, the original task set is terminated.
