      • Heroku's guiding influence the Twelve-Factor App methodology
        • A codebase is always versioned and it can have multiple deploys
        • Declare and isolate dependencies explicitly (always)
        • Configuration should be stored in the environment
        • Backend services should be treated as attached (loosely-coupled) resources
        • Strict separation of the build, release, and run stages of an app
        • An app in execution is a process or many processes
        • Services should be exported through port binding
        • An app should scale out through its process model
        • Faster startup and graceful shutdown is the way to app agility and scalability
        • Development and production (and everything in between) should be as similar as possible
        • The app should just log the event not manage it
