Intelligent-Tiering automatically moves S3 objects between access tiers based on how often they’re used, optimizing storage cost with no performance impact and no operational effort — ideal when access patterns are unknown or change over time.
When to choose it
If you can’t predict how often data will be accessed, Intelligent-Tiering saves money by shifting objects to cheaper tiers when they go cold (and back when accessed), for a small monitoring fee. If access patterns are known, a fixed class plus lifecycle rules may be cheaper. Unknown/changing access → Intelligent-Tiering.
Test yourself
A dataset in S3 has unpredictable access patterns, and the team wants automatic cost savings without managing lifecycle rules. Which storage class?
- S3 Standard
- S3 Intelligent-Tiering
- S3 Glacier Deep Archive
- S3 One Zone-IA
👉 Click to reveal the answer & explanation
Correct answer: B. Intelligent-Tiering automatically moves objects between tiers based on usage, optimizing cost for unpredictable access with no lifecycle rules to manage. Standard (A) never saves on cold data; Deep Archive (C) is too slow for active data; One Zone-IA (D) suits known-infrequent, non-critical data.
