Continuous Integration is a holistic Lean software development approach that aims to produce and put into production continuous software in an incremental and iterative way.Continuous Integration is a holistic Lean software development approach that aims to produce and put into production continuous software in an incremental and iterative way, where waste reduction is of paramount importance.The word 'holistic' refers to the PPT concepts: People (multiple expert), Process (knowledge of business and management processes) and Technology (application and infrastructure programming). The incremental and iterative method makes fast feedback possible because functionalities can be put into production earlier. This reduces waste because defects are found earlier and can be repaired faster.This book is a publication in the Continuous Everything series. The content consists of treating Continuous Integration based on a definition, business case, architecture, design, and best practices. Concepts discussed here are the change paradigm, the application of Continuous Integration, use of repositories, code quality, green code, green build, refactoring, security-based development and built-in failure mode. In this way you are quickly up to date in the field of DevOps developments with regard to Continuous Integration.Continuous Integration is a holistic Lean software development approach that aims to produce and put into production continuous software in an incremental and iterative way.With this book you are quickly up to date in the field of DevOps developments with regard to Continuous Integration.
