What’s DevOps?

Maximizing operational processes w.r.t.:• Predictability• Efficiency• Security• Maintainability

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

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

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

DevOps

Disadvantages

• Initial setup time required• Well-developed test-suite required to achieve automated

testing advantages
