# Post-deployment configuration (ECS architecture)
<a name="post-deployment-ecs"></a>

After deploying the ECS template, additional configuration steps are required to fully utilize the advanced features:

 **Admin UI Access:** The Admin UI link is available in the CloudFormation stack outputs section. Access the Admin UI from there and sign in using the provided Cognito credentials.

 **Initial Configuration:** 
+  **Configure Origins**: Use the Admin UI to add your S3 buckets and external origins
+  **Create Mappings**: Set up path-based or host-header mappings to route requests to origins
+  **Define Policies**: Create transformation policies for consistent image processing
