Fine print worth knowing

One bit of fine print is worth knowing before committing storage here: the free outbound allowance tops out at 3× your stored volume each month — past that wall every extra GiB bills at $0.01/GiB, and ordinary dev churn burns through it faster than you'd expect.

Where it shines: read-heavy workloads get real headroom from 3× stored volume in monthly free egress; there is no minimum spend or storage floor — the bill tracks actual usage exactly; and 10 GB of storage is simply free, commitment or not.
