Getting software released to users is often a painful, risky, and time-consuming process.

This groundbreaking new book sets out the principles and technical practices that enable

rapid, incremental delivery of high quality, valuable new functionality to users. Through

automation of the build, deployment, and testing process, and improved collaboration between

developers, testers, and operations, delivery teams can get changes released in a matter of hours?

sometimes even minutes?no matter what the size of a project or the complexity of its code base.

Jez Humble and David Farley begin by presenting the foundations of a rapid, reliable, low-risk

delivery process. Next, they introduce the ?deployment pipeline,? an automated process for

managing all changes, from check-in to release. Finally, they discuss the ?ecosystem? needed to

support continuous delivery, from infrastructure, data and configuration management to governance.

The authors introduce state-of-the-art techniques, including automated infrastructure management

and data migration, and the use of virtualization. For each, they review key issues, identify best

practices, and demonstrate how to mitigate risks. Coverage includes

? Automating all facets of building, integrating, testing, and deploying software

? Implementing deployment pipelines at team and organizational levels

? Improving collaboration between developers, testers, and operations

? Developing features incrementally on large and distributed teams
