In one line
Storage is half of it. Under Elastic throughput every GB you read or write is metered too.
What gets missed
Elastic throughput meters data both directions, not just reads. IA and Archive add a per-GB access fee, and files under 128 KiB bill as 128 KiB — a floor on small files, not a rounding rule.

Bills the same way
These services turn exactly the same meters, so what you learn here transfers.
