Twelve-Factor Apphttp://12factor.net

scalabilityportability

productivity

One codebase tracked in revision control, many deploys.

I. Codebase

One codebase, one app

Explicitly declare and isolate dependencies

II. DependenciesGemfile =>dependency declarationBundle exec => dependency isolation

III. Config

Store config in the environment

An app’s config is everything that is likely to vary between deploys (staging, production, developer environments, etc).

Don’t check in to the codebase

IV. Backing Services

Treat backing services as attached resources

IV. Backing Servicescon’t

V. Build, release, run

Strictly separate build and run stages

VI. Processes

stateless processes

share-nothing processes

VII. Port binding

Export services via port binding

Containerless

Add web server by dependency declaration

VIII. Concurrency

Scale out via the process model

IX. Disposability

Fast startup

Graceful shutdown

XI. Logs

Treat logs as event streams

Write logs to file

X. Dev/prod parity

Development = Staging = Production

Time gapPersonal gapTool gap

Design for continuous deployment

XII. Admin processes

Run admin/management tasks as one-off processes

bundle exec rake db:migrate
