Which solution will meet these requirements?
Use S3 replication to transition infrequently accessed objects to S3 Standard-Infrequent Access (S3 Standard-IA)
Use S3 Lifecycle rules to transition objects from S3 Standard to Standard-Infrequent Access (S3 Standard-IA)
Use S3 Lifecycle rules to transition objects from S3 Standard to S3 Intelligent-Tiering
Use S3 Inventory to identify and transition objects that have not been accessed from S3 Standard to S3 Intelligent-Tiering
Explanations:
S3 replication is used for duplicating objects across different S3 buckets or regions but does not help in transitioning objects based on access frequency. It does not reduce costs effectively since it does not address the need to move data to a cheaper storage class based on access patterns.
While S3 Lifecycle rules can transition objects to S3 Standard-IA, this option assumes the access pattern can be predicted. The company cannot control access patterns, which makes this option less ideal as it may not optimize costs effectively for unpredictable access.
S3 Intelligent-Tiering automatically moves objects between two access tiers (frequent and infrequent) based on changing access patterns. This option is ideal because it does not require prior knowledge of access patterns, making it well-suited for scenarios where access is unpredictable, thus potentially reducing costs.
S3 Inventory is a reporting feature that helps identify unused objects but does not automatically transition them to different storage classes. This option would require manual intervention and may not be timely or efficient for reducing costs based on access patterns.
I gauge that the answer is:
Use S3 Lifecycle rules to transition objects from S3 Standard to S3 Intelligent-Tiering
