Single answerA startup is using Amazon S3 to store large amounts of data for backup and archival purposes. They do not frequently access this data but want to minimize their storage costs. Which storage class or tier should they choose to achieve this goal?
- A
Amazon S3 Standard
- B
Amazon S3 Intelligent-Tiering
- C
Amazon S3 Glacier Deep Archive
- D
Amazon S3 One Zone-IA
Show answer and explanation
Correct answer: C
Explanation
For infrequently accessed data that is being stored for long-term backup or archival, Amazon S3 Glacier Deep Archive provides the lowest cost among all the S3 storage classes. It is specifically designed for data that does not require immediate retrieval, making it the optimal choice in this scenario.
- A. Incorrect.
Amazon S3 Standard is designed for frequently accessed data and has higher storage costs compared to archival options. It is not cost-effective for infrequently accessed, long-term storage.
- B. Incorrect.
Amazon S3 Intelligent-Tiering is useful for data with unpredictable access patterns. However, it is not the most cost-effective option for long-term archival storage, as it incurs monitoring fees.
- C. Correct.
Amazon S3 Glacier Deep Archive is the lowest-cost storage class in Amazon S3. It is specifically designed for long-term data archiving where retrieval time is not a priority, making it the ideal choice for infrequently accessed data.
- D. Incorrect.
Amazon S3 One Zone-IA is cost-effective for infrequently accessed data but stores data in a single availability zone. It does not match the cost savings provided by S3 Glacier Deep Archive for archival purposes.
