Leading a DevOps Transformation

Implementing DevOps is more than just implementing tools. It requires thinking – and acting – differently about everything from budgeting and program management to architecture and compliance. In this talk, Jez presents what DevOps is and, just as importantly, what it isn’t from the leadership perspective, and takes you through the journey you’ll need to embark on in order to achieve the outcomes DevOps promises.

9. software delivery as a competitive advantage
   “Firms with high-performing IT
   organizations were twice as likely to

   and productivity goals.”

10. software delivery as a competitive advantage
    high performers were more than twice as likely to

    • Achieving organizational and mission goals
    • Measures that demonstrate to external parties
    whether or not the organization is achieving
    intended results

    …rewriting all our systems and sticking them in the cloud
    …firing our sysadmins / testers / … and hiring “devops experts”
    …doing a re-org
    …giving developers (or anyone else for that matter) access to prod
    …buying a bunch of devops tools
    myths: devops isn’t…

    deploy and release its product or service on demand, independently of other services the
    product or service depends upon?
    make large-scale changes to the design of its system without the permission of somebody
    outside the team or depending on other teams?
    complete its work without needing fine-grained communication and coordination with
    people outside the team?
    perform deployments during normal business hours with negligible downtime?
    do most of its testing on demand, without requiring an integrated test environment?
    architectural outcomes: can my team…

    rules of strangler
    • start by delivering new functionality—at least at first
    • don’t rewrite existing functionality except to simplify
    • deliver something fast
    • design for testability and deployability
    • architect the new software to run on a paas

    disaster recovery testing
    “For DiRT-style events to be successful, an organization
    first needs to accept system and process failures as a
    means of learning… We design tests that require
    engineers from several groups who might not normally
    work together to interact with each other. That way,
    should a real large-scale disaster ever strike, these people
    will already have strong working relationships”
