SAFe® for DevOps Practitioners

By: Robert Wen

Overview of this book

Product development and release faces overlapping challenges due to the combined pressure of delivering high-quality products in shorter time-to-market cycles, along with maintaining proper operation and ensuring security in a complex high-tech environment. This calls for new ways of overcoming these challenges from design to development, to release, and beyond. SAFe® for DevOps Practitioners helps you use a DevOps approach with the Scaled Agile Framework and details how value streams help you resolve these challenges using examples and use cases. The book begins by explaining how the CALMR approach makes DevOps effective in resolving product development roadblocks. Next, you’ll learn to apply value stream management to establish a value stream that enables product development flow, measure its effectiveness through appropriate feedback loops, and find ways of improving it. Finally, you’ll get to grips with implementing a continuous delivery pipeline that optimizes the value stream through four phases during release on demand. This book complements the latest SAFe DevOps courses, and you’ll find it useful while studying for the SAFe DevOps Practitioner (SDP) certification. By the end of this DevOps book, you’ll have gained a clear understanding of how to achieve continuous execution and release on demand using DevOps and SAFe.

Building the solution package

The CI/CD pipeline can be triggered by version control system actions such as saving a new change as a commit. Before the changes are accepted by the version control system, they should go through a testing process to ensure they will not adversely affect the current code base. This process of testing and version control integration is an important part of the CI process where practices are divided into a version control perspective and a testing perspective.

Let’s look at each of these perspectives and the practices within.

Version control practices

Good version control practices ensure that changes introduced into version control are evaluated through testing before they are saved and merged with the existing code base. This ensures that the code base is robust, without changes that may prevent the code base from being built or packaged correctly.

Version control practices can further be divided into three types that help ensure a...
