Explanation
S3 One Zone-Infrequent Access (S3 One Zone-IA) is the most cost-effective storage class for this scenario because:
- Rarely accessed data: The company states they will rarely access the data, which aligns perfectly with infrequent access storage classes
- Recreatable data: Since the data can be recreated if necessary, the reduced durability of S3 One Zone-IA (data stored in only one Availability Zone) is acceptable
- Cost optimization: S3 One Zone-IA is cheaper than S3 Standard-IA because it stores data in only one Availability Zone rather than three
- Storage class comparison:
- S3 Express One Zone: Designed for high-performance, low-latency access - too expensive for rarely accessed data
- S3 Standard: Designed for frequently accessed data - not cost-effective for rarely accessed data
- S3 Standard-IA: Stores data across multiple Availability Zones - more expensive than S3 One Zone-IA and unnecessary for recreatable data
When data is rarely accessed and can be recreated, S3 One Zone-IA provides the best balance of cost savings while still maintaining adequate durability for the use case.
