The same architectural choices that make systems fast often make them cheaper. A field guide to spending less without slowing down.
Cloud bills balloon quietly. The fix isn't heroic cost-cutting sprints — it's making cost a first-class engineering metric, visible on the same dashboards as latency and errors.
Right-sizing, autoscaling, and caching typically reclaim the majority of waste. Reserved capacity and architectural changes handle the rest.
Frugality is a design constraint that produces better systems. When every request has a cost, you naturally build leaner, faster software.
