Months ! Requirements have
changed !
You can’t just ask customers what
they want and then try to give that to
them. By the time you get it built,
they’ll want something new.

Pipeline considerations
 Pipeline can be very different depending on many factors
 Technologies chosen, target platform, toolsets available
 Your organizational structure, processes and culture
• Manual procedures and approvals might still be needed.
 The architecture chosen and how components are decoupled
• Microservices, classic 3-tier, containers, PaaS, resources…
 Your own need for speed
 There is no generic pipeline. It is not just a question of tool choices.
 Design your pipeline as a value stream and apply Lean principles to
optimize it. Do not just deploy tools or automate blindly!
 Remember that Dev & Ops should be collaborating during complete
lifecycle!
 Demo

Advanced DevOps Pipeline Features
The pipeline should ideally enable the application to do things like…
 Split user traffic between multiple concurrent versions
 Test new features and ideas
 Measure increase/decrease statistics
 Leverage results to enhance application user
experience
 Control features with Feature Flags
 Deploy multiple revisions of the same code
 Slowly send traffic to new version
 Monitor new version for errors or issues
 Full cut over once new version has been fully
tested and assured
 Easy failback to later version
 Smaller code, faster to build & deploy
 Individually scalable components
 Independent and flexible development, testing,
deployment cycle among services
 Containerization making it easier to optimize
 Choose best technology stack per service
 Business monitoring
 Application, Service & Process monitoring
 VM & infrastructure monitoring
 Synthetic user experience monitoring
 A/B testing results (conversion inc./dec.)
