AWS Certified SysOps Administrator – AssociateCost and Performance OptimizationHard
A media company uses Amazon S3 to store large video files. They are experiencing high costs due to frequent data retrieval from S3 Standard-IA, as their video editing team often needs to access older files for re-edits or archival review. The access pattern is unpredictable; some older files might be accessed multiple times within a month, while others remain untouched for months. The company wants to optimize storage costs without significantly compromising retrieval performance or incurring high retrieval fees for unpredictable access. Which S3 storage class is most suitable?
- AS3 Glacier Deep Archive.
- BS3 Standard.
- CS3 Glacier Instant Retrieval.
- DS3 Intelligent-Tiering.
Show answer & explanationAnswer & explanation
Correct answer: D. S3 Intelligent-Tiering.
S3 Intelligent-Tiering is designed for data with unknown or changing access patterns. It automatically moves objects between two access tiers (frequent and infrequent) based on access patterns, optimizing costs without performance impact or retrieval fees for tiering. This perfectly matches the unpredictable access needs of the video editing team.
Why the other options are wrong
- A. S3 Glacier Deep Archive is for the lowest-cost archival, with retrieval times in hours and higher retrieval costs, making it unsuitable for data that might need to be accessed multiple times within a month.
- B. S3 Standard is for frequently accessed data and would be more expensive than necessary for data that is often infrequently accessed.
- C. S3 Glacier Instant Retrieval is for archival data that needs immediate access, but it still incurs retrieval fees and might be more expensive than Intelligent-Tiering for data that might sometimes be frequently accessed.
S3 Intelligent-Tiering
An S3 storage class that automatically moves objects between two access tiers (frequent and infrequent) based on changing access patterns.
- Optimizes costs for unknown/changing access patterns.
- No retrieval fees for tiering.
- Provides millisecond access latency.
Memory trick: S3 storage choices: hot, cold, or smart. Pick your access pattern.
