 After all requirements are met, you can [enable Auto DevOps](#enablingdisabling-auto-devops).
 
+### AWS ECS
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/208132) in GitLab 13.0.
+
+You can choose to target [AWS ECS](../../ci/cloud_deployment/index.md) as a deployment platform instead of using Kubernetes.
+
+To get started on Auto DevOps to ECS, you'll have to add a specific Environment
+Variable. To do so, follow these steps:
+
+1. In your project, go to **Settings > CI / CD** and expand the **Variables**
+   section.
+
+1. Specify which AWS platform to target during the Auto DevOps deployment
+   by adding the `AUTO_DEVOPS_PLATFORM_TARGET` variable.
+
+1. Give this variable the value `ECS` before saving it.
+
+When you trigger a pipeline, if you have AutoDev Ops enabled and if you have correctly
+[entered AWS credentials as environment variables](../../ci/cloud_deployment/index.md#deploy-your-application-to-aws-elastic-container-service-ecs),
+your application will be deployed to AWS ECS.
+
+NOTE: **Note:**
+If you have both a valid `AUTO_DEVOPS_PLATFORM_TARGET` variable and a Kubernetes cluster tied to your project,
+only the deployment to Kubernetes will run.
