   Believe that:
   ▰ Any problem must be solved at the right level
   ▰ Software is easy. People are hard
   ▰ A problem should be highlighted, an idea should
   be "sold", a solution should be demonstrated

22. What is Quality?
    22
    Explicitly declare and
    isolate dependencies
    ▰ declaration VS isolation
    ▰ never relies on implicit
    existence
    ▰ system tool can be a
    dependency

23. What is Quality?
    23
    Store config in the
    environment
    ▰ Config is not part of the
    artifact
    ▰ could be made open source
    at any moment, without
    compromising any
    credentials.

24. What is Quality?
    24
    Treat backing services as
    attached resources
    ▰ local and third party parity
    ▰ Attach URL or other
    locator/credentials stored in
    the config
    

    View Slide

25. What is Quality?
    25
    Strictly separate build and
    run stages
    ▰ Artifact
    ▰ Build
    ▰ Release
    ▰ Run time
    ▰ Dry run

26. What is Quality?
    26
    Execute the app as one or
    more stateless processes
    ▰ stateless
    ▰ share-nothing
    ▰ state stored at
    backing-service

27. What is Quality?
    27
    Scale out via the process
    model
    ▰ Unix
    ▰ process
    ▰ should never daemonize
    ▰ Use process manager like
    systemd

28. What is Quality?
    28
    ▰ Same backing services
    ▰ Same lib versions
