Which storage solution meets these requirements MOST cost-effectively?
Use the S3 Intelligent-Tiering storage class. Create an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 1 year.
Use the S3 Intelligent-Tiering storage class. Configure S3 Intelligent-Tiering to automativally move objects to S3 Glacier Deep Archive after 1 year.
Use the S3 Standard-Infrequent Access (S3 Standard-IA) storage class. Create an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive after 1 year.
Use the S3 Standard storage class. Create an S3 Lifecycle policy to transition objects to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days, and then to S3 Glacier Deep Archive after 1 year.
Explanations:
S3 Intelligent-Tiering automatically moves data based on access patterns, but it doesn’t support automatic transition to Glacier Deep Archive after a fixed duration like 1 year. A lifecycle policy is required to transition data after 1 year.
S3 Intelligent-Tiering does not have the capability to automatically transition objects to Glacier Deep Archive after 1 year. It moves objects based on access frequency but not by a set time.
S3 Standard-IA is designed for infrequent access, but it is not the most cost-effective solution for this scenario. The data is actively used in the first 30 days and then periodically retrained, so transitioning to Standard-IA and then Glacier Deep Archive would not optimize cost effectively.
S3 Standard is ideal for frequently accessed data (like for retraining), and then transitioning to Standard-IA after 30 days and to Glacier Deep Archive after 1 year minimizes costs while meeting the access and archival requirements.
