Unit economics
Cost per business unit — per order, per tenant, per active user — so efficiency becomes a trackable engineering outcome.

Unit economics expresses cloud cost as a ratio against a business driver — cost per active user, per order, per GB processed, per tenant. It removes the noise of absolute bills and shows whether the workload is becoming more or less efficient as usage grows.
Why it matters
A cloud bill that doubled can either be a problem or a sign the business is thriving. Without a unit, you can't tell the difference. Unit economics lets engineering and finance share a vocabulary for efficiency that survives traffic growth, feature launches, and architectural change.
How to pick a unit
Start with the unit the business already uses to describe value. If product tracks daily active users, use cost per DAU. If finance thinks in transactions, use cost per transaction. Avoid units that move as often as the bill (e.g. cost per instance) — they describe infrastructure rather than value.
