SAA-C03 Q526 · Storage

Question

A data science team requires storage for nightly log processing. The size and number of logs is unknown and the logs will persist for 24 hours only. What is the MOST cost-effective solution?

Accepted Answer

**Amazon S3 Standard** is the most cost-effective choice here for three critical reasons:

1. **No minimum storage duration charge**: S3 Standard has NO minimum storage duration requirement. You only pay for the exact time the data is stored. Since logs persist for only 24 hours, this is crucial.

2. **No retrieval fees**: The logs need to be processed (read), and S3 Standard charges $0 for data retrieval. Other classes like S3 One Zone-IA charge per-GB retrieval fees.

3. **No minimum object size charge**: S3 Standard has no minimum billable object size, unlike IA classes which bill a minimum of 128 KB per object.

**Why other classes fail the cost test for 24-hour data:**
- S3 One Zone-IA has a **30-day minimum storage duration** — you'd be billed for 30 days even though data exists for
