“If you need to deploy software more frequently, this book is for you. Applying it will help you reduce risk, eliminate tedious work, and increase confidence. I’ll be using the principles and practices here on all my current projects.”

–Kent Beck, Three Rivers Institute

“Whether or not your software development team already understands that continuous integration is every bit as necessary as source code control, this is required reading. This book is unique in tying the whole development and delivery process together, providing a philosophy and principles, not just techniques and tools. The authors make topics from test automation to automated deployment accessible to a wide audience. Everyone on a development team, including programmers, testers,  system administrators, DBAs, and managers, needs to read this book.”

–Lisa Crispin, co-author of Agile Testing

“For many organizations Continuous Delivery isn’t just a deployment methodology, it’s critical to doing business. This book shows you how to make Continuous Delivery an effective reality in your environment.”

–James Turnbull, author of Pulling Strings with Puppet

“A clear, precise, well-written book that gives readers an idea of what to expect for the release process. The authors give a step-by-step account of expectations and hurdles for software deployment. This book is a necessity for any software engineer’s library.”

–Leyna Cotran, Institute for Software Research, University of California, Irvine

“Humble and Farley illustrates what makes fast-growing web applications successful. Continuous deployment and delivery has gone from controversial to commonplace and this book covers it excellently. It’s truly the intersection of development and operations on many levels, and these guys nailed it.”

–John Allspaw, VP Technical Operations, Etsy.com and author of

The Art of Capacity Planning and Web Operations

“If you are in the business of building and delivering a software-based service, you would be well served to internalize the concepts that are so clearly explained in Continuous Delivery. But going beyond just the concepts, Humble and Farley provide an excellent playbook for rapidly and reliably delivering change.”

–Damon Edwards, President of DTO Solutions and co-editor of dev2ops.org

“I believe that anyone who deals with software releases would be able to pick up this book, go to any chapter and quickly get valuable information; or read the book from cover to cover and be able to streamline their build and deploy process in a way that makes sense for their organization. In my opinion, this is an essential handbook for building, deploying, testing, and releasing software.”

–Sarah Edrie, Director of Quality Engineering, Harvard Business School

“Continuous Delivery is the logical next step after Continuous Integration for any modern software team. This book takes the admittedly ambitous goal of constantly delivering valuable software to customers, and makes it achievable through a set of clear, effective principles and practices.”

–Rob Sanh

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

• Implementing an effective configuration management strategy

• Automating acceptance testing, from analysis to implementation

• Testing capacity and other non-functional requirements

• Implementing continuous deployment and zero-downtime releases

• Managing infrastructure, data, components and dependencies

• Navigating risk management, compliance, and auditing

Whether you’re a developer, systems administrator, tester, or manager, this book will help your

organization move from idea to release faster than ever―so you can deliver value to your business

rapidly and reliably.
