Which solution meets these requirements MOST cost-effectively?
Use S3 Standard. Use an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days.
Use S3 Standard. Use an S3 Lifecycle rule to transition the reports to S3 Standard-Infrequent Access (S3 Standard-IA) after 7 days.
Use S3 Intelligent-Tiering. Configure S3 Intelligent-Tiering to transition the reports to S3 Standard-Infrequent Access (S3 Standard-IA) and S3 Glacier.
Use S3 Standard. Use an S3 Lifecycle rule to transition the reports to S3 Glacier Deep Archive after 7 days.
Explanations:
S3 Standard is used for frequently accessed reports in the first week. After 7 days, transitioning to S3 Glacier is cost-effective for long-term storage, and retrieval within 6 hours is possible with S3 Glacier.
S3 Standard-IA is designed for infrequent access, and it has a retrieval time of minutes, not hours. This does not meet the 6-hour retrieval requirement for the reports.
S3 Intelligent-Tiering automatically moves objects between two access tiers, but it doesn’t meet the specific need for retrieval within 6 hours from Glacier, making it less cost-effective and incorrect for this use case.
S3 Glacier Deep Archive is the lowest-cost storage option but has retrieval times of 12 hours or more, which does not meet the 6-hour retrieval requirement.
I measure that the answer is:
Use S3 Standard. Use an S3 Lifecycle rule to transition the reports to S3 Glacier after 7 days.
