Dev/Staging/Prod

Concepts: paEnvironmentMgmt

What They Want to Hear 'Three environments: dev (fast iteration, sample data), staging (production-like infrastructure, recent data snapshot), prod (real data, real consumers). Staging catches issues that dev misses: permission errors, data volume differences, infrastructure differences. A common cost optimization is thin staging: production-like infrastructure but only the last 7 days of data instead of the full history.'
