    MARTIN ETMAJER Founder | GetCloudnative e.U. Slide 6 Traditional Software

    Development Analysis Design Implementation Verification Operations Observation 2: Change Resistance The entire product is specified in advance (assumes no change). Efforts put into heavy documentation fosters change resistance.

    MARTIN ETMAJER Founder | GetCloudnative e.U. Slide 27 Faster Time-to-Market

    An automated build, deploy, test and release process greatly reduces the feature cycle time. Lower Risks Automation makes software releases reliable and repeatable (if not to say boring). Higher Quality Automated testing in production-like environments greatly reduces defects in production. Better Products The ability to release features at any time enables working in small steps and running experiments. Happier Teams Continuous Delivery makes releases less painful. Teams can focus on being creative and solving problems. Continuous Delivery Benefits
  21. 29.

    MARTIN ETMAJER Founder | GetCloudnative e.U. Slide 29 Create an

    Automated, Repeatable and Reliable Release Process Releasing software into production should be as easy as selecting a version and pushing a button. Automate your build, deploy, test and release process up to the point where human decision making is required. Everyone is Responsible Don‘t incentivize silo behavior. Everyone must work together on achieving the company‘s goals. Make improving work a part of your routine and never be satisfied with the status quo. Keep Everything in Version Control Maintain a single source of truth for your source code, configuration, data, scripts, and documentation. Build Quality In! Integrate feedback loops to catch process defects as early as possible (while they‘re cheap) – then fix them. Continuous Delivery Principles
