archive is cheap to store and never free to read. everyone watches the storage line; the retrieval and minimum-duration lines are what ambush you.

colder class = higher per-GB read fee. glacier flexible and deep archive add a per-request fee on top, and deep archive's slowest tier is measured in hours, not seconds. put frequently-read data in glacier to save on storage and then pay retrieval on every read — that's the most expensive mistake in the whole subject. the retrieval bill can beat what standard would've cost outright.

and minimum duration: delete a standard-IA object before 30 days you still pay 30, glacier bills 90, deep archive 180. before you tier anything down, ask the one question that governs all of it — how often is this actually read?
