Winner of the 2011 Jolt Excellence Award! 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.

Peter Seibel interviews 15 of the most interesting computer programmers alive today in Coders at Work, offering a companion volume to Apress's highly acclaimed best-seller Founders at Work by Jessica Livingston. As the words "at work" suggest, Peter Seibel focuses on how his interviewees tackle the day-to-day work of programming, while revealing much more, like how they became great programmers, how they recognize programming talent in others, and what kinds of problems they find most interesting. Hundreds of people have suggested names of programmers to interview on the Coders at Work web site: www.codersatwork.com. The complete list was 284 names. Having digested everyone's feedback, we selected 15 folks who've been kind enough to agree to be interviewed: * Frances Allen: Pioneer in optimizing compilers, first woman to win the Turing Award (2006) and first female IBM fellow * Joe Armstrong: Inventor of Erlang * Joshua Bloch: Author of the Java collections framework, now at Google * Bernie Cosell: One of the main software guys behind the original ARPANET IMPs and a master debugger * Douglas Crockford: JSON founder, JavaScript architect at Yahoo! * L. Peter Deutsch: Author of Ghostscript, implementer of Smalltalk-80 at Xerox PARC and Lisp 1.5 on PDP-1 * Brendan Eich: Inventor of JavaScript, CTO of the Mozilla Corporation * Brad Fitzpatrick: Writer of LiveJournal, OpenID, memcached, and Perlbal * Dan Ingalls: Smalltalk implementor and designer * Simon Peyton Jones: Coinventor of Haskell and lead designer of Glasgow Haskell Compiler * Donald Knuth: Author of The Art of Computer Programming and creator of TeX * Peter Norvig: Director of Research at Google and author of the standard text on AI * Guy Steele: Coinventor of Scheme and part of the Common Lisp Gang of Five, currently working on Fortress * Ken Thompson: Inventor of UNIX * Jamie Zawinski: Author of XEmacs and early Netscape/Mozilla hacker What you'll learnHow the best programmers in the world do their jobs! Who this book is for Programmers interested in the point of view of leaders in the field. Programmers looking for approaches that work for some of these outstanding programmers.
