We're going to need default hard budget caps on pretty much everything
Summary
The author argues that pay‑by‑usage services should default to hard spend caps that shut down usage once a monthly limit is hit, citing recent AWS and Google Cloud spend‑limit features as examples.
- Hard budget caps automatically stop services when a spend limit is reached, preventing runaway costs.
- Soft warnings (email alerts) don’t protect against surprise large bills.
- AWS and Google Cloud now offer spend‑limit features, but they’re still limited roll‑out.
- Default should be a hard cap with an explicit opt‑out checkbox for risky use cases.
Developers and product teams using cloud APIs need safeguards to avoid unexpected high charges.
