A new ECS task definition revision for a document OCR service is ready. Where should it be verified before production?
Select an answer to reveal the explanation.
Short Explanation
New task revisions earn their keep in a test cluster under synthetic load—not on election-day production. ECR having the image is necessary, not sufficient. Burning the old revision before you prove the new one is how rollbacks vanish.
Full Explanation
Containerized applications should be tested as ECS task definition revisions in non-production clusters/services, including synthetic load when appropriate, before production promotion. An ECR tag alone does not prove runtime configuration, IAM, or scaling behavior. Laptop-only runs miss AWS networking and service discovery nuances; removing prior revisions early removes a rollback path.
