The Twelve Factors[edit]

The Twelve Factors[1][2]
# Factor Description
I Codebase There should be exactly one codebase for a deployed service with the codebase being used for many deployments.
II Dependencies All dependencies should be declared, with no implicit reliance on system tools or libraries.
III Config Configuration that varies between deployments should be stored in the environment.
IV Backing services All backing services are treated as attached resources and attached and detached by the execution environment.
V Build, release, run The delivery pipeline should strictly consist of build, release, run.
VI Processes Applications should be deployed as one or more stateless processes with persisted data stored on a backing service.
VII Port binding Self-contained services should make themselves available to other services by specified ports.
VIII Concurrency Concurrency is advocated by scaling individual processes.
IX Disposability Fast startup and shutdown are advocated for a more robust and resilient system.
X Dev/Prod parity All environments should be as similar as possible.
XI Logs Applications should produce logs as event streams and leave the execution environment to aggregate.
XII Admin Processes Any needed admin tasks should be kept in source control and packaged with the application.
