Extreme Programming

Extreme Programming is a discipline of software development based on values of simplicity, communication, feedback, courage and respect. It works by bringing the whole team together in the presence of simple practices, with enough feedback to enable the team to see where they are and to tune the practices to their unique situation.

What is Continuous Integration?

Continuous Integration (CI) is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early.

Continuous Integration Practices

Maintain a single source repositoryAutomate the buildMake your build self-testingEvery commit should build on an integration

machineKeep the build fastTest in a clone of production environmentEveryone can see what’s happeningAutomate deployment

Source Control Tools (Centralized vs Distributed)

Build Automation (Why?)

Early warning of broken/incompatible codeEarly warning of conflicting changesConstant availability of a "current" build for

testing, demo or release purposesHave history of builds and releases in order to

investigate issuesEliminate dependencies on key personnelSave time and money - because of the

reasons listed above

Continuous Delivery

Continuous Delivery is a software development discipline where you build software in such a way that the software can be released to production at any time.

Martin Fowler

Continuous Delivery

Your software is deployable throughout its lifecycle

Your team prioritizes keeping the software deployable over working on new features

Anybody can get fast, automated feedback on the production readiness of their systems any time somebody makes a change to them

You can perform push-button deployments of any version of the software to any environment on demand
