I. CodebaseOne codebase tracked in revision control, many deploys

II. DependenciesExplicitly declare and isolate dependencies

III. ConfigStore config in the environment

IV. Backing ServicesTreat backing services as attached resources

V. Build, release, runStrictly separate build and run stages

VI. ProcessesExecute the app as one or more stateless processes

VII. Port bindingExport services via port binding

VIII. ConcurrencyScale out via the process model

IX. DisposabilityMaximize robustness with fast startup and graceful shutdown

X. Dev/prod parityKeep development, staging, and production as similar as possible

XI. LogsTreat logs as event streams

XII. Admin processesRun admin/management tasks as one-off processes

Databases•Very own requirements:

• State-full• Low CPU but high I/O• Distributed data• (usually) complex to scale• (usually) not built for “hot swap”

• not 12 Factor applications

Databases•Don’t dockerize databases

•Keep them external to the system• DBA will love you not hate you• Easier to maintain• Very own cluster mechanisms• Easier routing in Datacenters
