The Twelve Factors - http://12factor.net/ I. Codebase One codebase tracked in revision control, many deploys  II. Dependencies Explicitly declare and isolate dependencies  III. Conﬁg Store conﬁg in the environment IV. Backing Services Treat backing services as attached resources  V. Build, release, run Strictly separate build and run stages  VI. Processes Execute the app as one or more stateless processes VII. Port binding Export services via port binding VIII. Concurrency Scale out via the process model IX. Disposability Maximize robustness with fast startup and graceful shutdown X. Dev/prod parity Keep development, staging, and production as similar as possible XI. Logs Treat logs as event streams XII. Admin processes Run admin/management tasks as one-off processes
