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. Steve Jobs

All rights reserved. 14 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

16. CWIN16 - Implementing a DevOps Pipeline | September 2016 Copyright © 2016 Capgemini and Sogeti. All rights reserved. 18 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.) A/B Testing Blue/Green Deployments Deploy & Scale Parts of the Application App Monitoring
