Continuous Delivery: Reliable Software Releases through Build, Test, and Deployment Automation

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 includesAutomating all facets of building, integrating, testing, and deploying softwareImplementing deployment pipelines at team and organizational levelsImproving collaboration between developers, testers, and operationsDeveloping features incrementally on large and distributed teamsImplementing an effective configuration management strategyAutomating acceptance testing, from analysis to implementationTesting capacity and other non-functional requirementsImplementing continuous deployment and zero-downtime releasesManaging infrastructure, data, components and dependenciesNavigating risk management, compliance, and auditingWhether 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.
