### AI overview

The article's method is to identify cold, transition-eligible S3 data with S3 Storage Lens, then observe candidate prefixes with S3 Storage Class Analysis for at least 30 days (the author used over 45 days to catch periodic reads). Size and age matter: analysis omits objects at or below 128 KB, and Glacier Instant Retrieval has a 128 KB minimum billable size and a 90-day minimum storage duration. The analysis chiefly informs Standard-to-Standard-IA transitions; for data with near-zero retrieval that still needs millisecond access, the article proposes Glacier Instant Retrieval, which has higher retrieval and request charges. Set a conservative lifecycle age based on observed access, and guard against costly scans with query routing and request-metric alarms. One engagement reports roughly 70% lower monthly storage cost for 5.8 PB while preserving millisecond access; the article cautions results depend on workload.

### Source excerpt

Learn a repeatable, evidence-based method to cut petabyte-scale Amazon S3 storage costs. Use S3 Storage Lens to find untiered buckets with near-zero retrieval, prove the cold access pattern with S3 Storage Class Analysis, and move the data to S3 Glacier Instant Retrieval with a lifecycle rule while keeping millisecond access.
