Staging Environment

Definitions

1. A pre-production environment that mirrors the production infrastructure as closely as possible — same services, configuration, and (ideally) anonymized production-scale data — used as the final validation step before deploying to production. It allows QA, integration testing, and stakeholder review without risking real users.

   In plain English: A copy of the real production system where teams test changes one last time before releasing them to actual users.

   Example: "The bug doesn't reproduce locally but it does on staging, so it's probably a config difference — check the environment variables."
