Which Amazon S3 storage class will meet these requirements?
S3 Standard
S3 Glacier Flexible Retrieval
S3 One Zone-Infrequent Access (S3 One Zone-IA)
S3 Standard-Infrequent Access (S3 Standard-IA)
Explanations:
S3 Standard is designed for frequently accessed data and does not provide the cost-effective storage solution needed for infrequently accessed data. It also does not align with the requirement for a retrieval time of up to 12 hours.
S3 Glacier Flexible Retrieval is designed for data that is not frequently accessed and allows retrieval within a timeframe that can be as fast as a few minutes up to 12 hours, making it suitable for the company’s requirements. It is also cost-effective for storage.
S3 One Zone-IA is for infrequently accessed data but only stores data in a single availability zone, which may not be appropriate for data retrieval within 12 hours if reliability is a concern. It is also more expensive than Glacier for the required access frequency.
S3 Standard-IA is for infrequent access but is intended for data that might be accessed more often than what the company requires. It does not meet the cost-effectiveness criterion for long-term storage as well as Glacier.
