- 11. What’s DevOps? DevOps is a software development method that stresses communication, collaboration and integration between software developers and information technology (IT) operations professionals. Maximizing operational processes w.r.t.: • Predictability • Efficiency • Security • Maintainability 11 DevOps Source: http://en.wikipedia.org/wiki/DevOps
- 12. What demands it? The adoption of DevOps is being driven by factors such as: • Use of agile and other development processes and methodologies • Demand for an increased rate of production releases from application and business unit stakeholders • Wide availability of virtualized and cloud infrastructure from internal and external providers • Increased usage of data center automation and configuration management tools 12 DevOps Source: http://en.wikipedia.org/wiki/DevOps

- 16. What are principles of continuous integration? • Maintain a code repository • Automate the build • Make the build self-testing • Everyone commits to the baseline every day • Every commit (to baseline) should be built • Keep the build fast • Test in a clone of the production environment • Make it easy to get the latest deliverables • Everyone can see the results of the latest build • Automate deployment 16 DevOps
- 17. Advantages • When unit tests fail or a bug emerges, developers might revert the codebase to a bug-free state • Developers detect and fix integration problems continuously • Early warning of broken/incompatible code • Early warning of conflicting changes • Immediate unit testing of all changes • Constant availability of a "current" build for testing/demo/rel • Immediate feedback to developers on the quality, functionality, or system-wide impact of code they are writing • Frequent code check-in pushes developers to create modular, less complex code 17 DevOps
- 18. Disadvantages • Initial setup time required • Well-developed test-suite required to achieve automated testing advantages 18 DevOps
