The job runs for about 1 hour and must not be interrupted, so Lambda is not suitable because AWS Lambda has a maximum execution time of 15 minutes. Fargate Spot is also not appropriate because the workload explicitly cannot tolerate interruption. The most cost-effective remaining design is to run the Python script on an EC2 On-Demand instance only during the nightly processing window and automate instance start/stop around the schedule. That avoids paying for compute all day while preserving uninterrupted execution during the job. The Step Functions Express option is not the natural fit for a single long-running Python job of this type. Therefore, an EC2 instance scheduled to run only when needed is the most economical answer among the choices.

AWS Compute Optimizerprovides detailed recommendations for optimizingAmazon EBS volumes, including insights into underutilized volumes, inefficient configurations, and potential cost savings. It analyzes usage patterns and provides recommendations based on historical data, making it the ideal tool for this use case.

Option A (Amazon Inspector): Amazon Inspector is for security assessments, not for cost optimization.

Option B (Systems Manager): Systems Manager does not specifically provide EBS optimization recommendations.

Option C (CloudWatch): CloudWatch metrics help monitor usage but do not offer optimization recommendations like Compute Optimizer.

Amazon DynamoDB provides single-digit millisecond performance at any scale and is fully managed to handle millions of catalog records. It is ideal for structured catalog data such as product metadata and scales seamlessly during high-traffic events like sales. Amazon S3 is optimized for storing unstructured large objects such as videos and manuals, with virtually unlimited scalability and high durability. Option A (RDS) would not handle massive scale or traffic spikes as efficiently. Option C overloads DynamoDB by forcing it to store large binary data, which is not its purpose. Option D (DocumentDB) is suitable for JSON-like documents but not optimal for storing large media files and would add operational complexity. Therefore, option B represents the best separation of structured and unstructured data storage.
