ECR Lifecycle Policies automatically manage image retention based on tag status, age, or count. They execute natively within the ECR service, requiring no external management or scripts — the least overhead and AWS-recommended cleanup method.

Account Factory Customization (AFC) automates Control Tower account provisioning with baseline blueprints for networking, logging, and guardrails. It integrates natively and minimizes overhead, per AWS Control Tower documentation.

 For deploying a Ruby-based application with requirements for interaction with an Amazon RDS for MySQL database, automatic scaling, high availability, and data persistence, the following steps will meet the requirements:

B. Deploy the application on AWS Elastic Beanstalk. Deploy a separate Amazon RDS for MySQL DB instance outside of Elastic Beanstalk. This approach ensures that the database persists independently of the Elastic Beanstalk environment, which can be torn down and recreated without affecting the database123.

E. Use the immutable deployment method to deploy new application versions. Immutable deployments provide a zero-downtime deployment method that ensures that if any part of the deployment process fails, the environment is rolled back to the original state automatically4.

D. Configure an Amazon EventBridge rule to monitor AWS Health events. Use an Amazon Simple Notification Service (Amazon SNS) topic as a target to alert the application team. This setup allows for automated monitoring and alerting of the application team in case of deployment failures or other health events56.
