The objects are “rarely accessed after 1 week” but must remain immediately available at all times. That means the storage class must support millisecond access without a restore process. S3 Standard-Infrequent Access (Standard-IA) is designed for exactly this: lower storage cost than S3 Standard, while still providing rapid access when needed.

With option B, an S3 Lifecycle rule transitions objects from S3 Standard to S3 Standard-IA after 7 days. This aligns perfectly with the usage pattern: frequent access initially, then infrequent access after a week, while keeping immediate availability.

Option C (S3 Glacier Flexible Retrieval) is not appropriate because Glacier classes are archival. Access typically requires a restore operation and retrieval time (minutes to hours), which violates “immediately available at all times.”

Option A expires objects, which deletes them after 7 days—this contradicts the requirement to keep objects available.

Option D is irrelevant because delete markers exist only when versioning is enabled. The bucket does not have versioning enabled, so this rule would not help.

Therefore, transitioning to S3 Standard-IA after 7 days is the correct cost-optimized solution while maintaining immediate availability.

Amazon S3 is a service that provides highly scalable, durable, and secure object storage. Amazon DynamoDB is a fully managed NoSQL database service that provides fast and consistent performance with seamless scalability. AWS Lambda is a service that lets developers run code without provisioning or managing servers. The developer can configure an S3 event to invoke a Lambda function that inserts records into DynamoDB whenever a new file is added to the S3 bucket. This solution will meet the requirement of inserting a record into DynamoDB as soon as a new file is added to S3.

CodeDeploy Predefined Configurations: CodeDeploy offers built-in deployment configurations for common scenarios.

Canary Deployment: Canary deployments gradually shift traffic to a new version, ideal for controlled rollouts like this requirement.

CodeDeployDefault.ECSCanary10Percent15Minutes: This configuration matches the company's requirements, shifting 10% of traffic initially and then completing the rollout after 15 minutes.
