Fine print worth knowing

A few things in the fine print deserve attention before committing storage here: API calls are metered — writes run $5.20/million and reads $0.42/million, which adds up for chatty applications doing many small operations; on top of that, pulling data out costs $90.00/TB — for public-serving workloads this toll, not storage, becomes the dominant line on the bill.

Where it shines: there is no minimum spend or storage floor — the bill tracks actual usage exactly; and 25 GB of storage is simply free, commitment or not.
