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 https://soundcloud.com/images/fb_placeholder.png <![CDATA[<iframe width="100%" height="400" scrolling="no" frameborder="no" allow="autoplay; encrypted-media" src="https://w.soundcloud.com/player/?visual=true&url=https%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F355986980&show_artwork=true"></iframe>]]> Peter Pilgrim - PEAT UK https://soundcloud.com/peter-pilgrim
