AWS CodeCommit is a service that provides fully managed source control for hosting secure and scalable private Git repositories. The development team can use CodeCommit to store the program code and prepare for the CI/CD pipeline. CodeCommit integrates with other AWS services such as CodePipeline, CodeBuild, and CodeDeploy to automate the code build and deployment process.

Amazon S3 Glacier Instant Retrieval is an archive storage class that delivers the lowest-cost storage for long-lived data that is rarely accessed and requires retrieval in milliseconds. With S3 Glacier Instant Retrieval, you can save up to 68% on storage costs compared to using the S3 Standard-Infrequent Access (S3 Standard-IA) storage class, when your data is accessed once per quarter.

Understanding Storage Requirements:

Files are large and infrequently accessed, but need to be available within minutes when requested in the first year.

Long-term (7-year) retention is required.

Cost-effectiveness is a top priority.

Why S3 Glacier Instant Retrieval:

Matches the retrieval requirements (access within minutes).

More cost-effective than S3 Standard for infrequently accessed data.

Simpler to use than traditional Glacier where retrievals take hours.

Why S3 Glacier Deep Archive:

Most cost-effective S3 storage class for long term archival.

Meets the 7-year retention requirement.

S3 Lifecycle Policy:

Automate the transition from Glacier Instant Retrieval to Glacier Deep Archive after one year.

Optimize costs by matching storage classes to access patterns.

The solution that will meet the requirements with the least development effort is to set the image resize Lambda function as a destination of the avatar generator Lambda function for the events that fail processing. This way, the fallback mechanism is automatically triggered by the Lambda service without requiring any additional components or configuration. The other options involve creating and managing additional resources such as queues, topics, state machines, or rules, which would increase the complexity and cost of the solution.
