Who it suits.
Serving files to the public, where egress is the bill everyone underestimates. Nothing to pay for bandwidth out, on any storage class, so a busy bucket costs what it costs to store rather than what it costs to read.
Consider something else if…
Operations are charged and rounded up to the whole million, so a workload of many tiny reads and writes pays here instead. The saving is on bandwidth, not on request volume.
