Question #2004
A media company stores video assets on AWS. The assets are accessed frequently during promotional campaigns but may remain unused for several months afterward. The company requires a storage solution that optimizes costs without compromising durability or availability. Which storage option best meets these requirements?
Amazon S3 Standard
Amazon S3 Intelligent-Tiering
Amazon S3 Glacier Deep Archive
Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA)
Explanation
Amazon S3 Intelligent-Tiering (B) is the best choice because it automatically transitions objects between Frequent Access and Infrequent Access tiers based on access patterns. During promotional campaigns, when video assets are accessed frequently, they remain in the Frequent Access tier. Afterward, when unused for months, they move to the Infrequent Access tier, reducing costs without manual intervention. It maintains 99.999999999% durability and high availability, meeting the company's requirements.
Other options:
- A (S3 Standard): Expensive for long-term storage with infrequent access.
- C (Glacier Deep Archive): Retrieval delays (12+ hours) compromise availability.
- D (One Zone-IA): Lower durability (99.999999999% vs. 99.999999999% for multi-AZ) and availability (single AZ), violating requirements.
Key Points:
1. Use S3 Intelligent-Tiering for unpredictable access patterns.
2. Avoid manual tier management and retrieval delays.
3. Ensure 11 9's durability and multi-AZ availability.
Answer
