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

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

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

18. Disadvantages
• Initial setup time required
• Well-developed test-suite required to achieve automated testing
