12.1 Factor Apps: Dev/Prod Parity

The 12.1 factor approach prefers locality over fully integrated
environments. Doing so promotes fast and independent iterations
on discrete services using automated tests to verify correctness.
End-to-End issues that may have been identified with a fully
integrated environment with dev/prod parity should be pushed
downstream in the deployment pipeline in accordance with test
pyramid principles. If a regression is identified, then it may
quickly addressed by adding tests to the relevant service’s test
suite.
