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.

Continuous integration

When code changes are ready, automation can begin building the necessary packages for use in staging and production environments. As part of the build process, tests can be run to determine the correct function as well as security. When testing indicates correct and secure functionality, a package is created and stored in artifact repositories based on the technology used.

This part of the pipeline is illustrated in the following figure:

Let’s look at how the CI portion of the pipeline manages a build, executes the initial-level testing, and packages the build. We will begin with a definition of continuous integration, continuous delivery, and continuous deployment.

Continuous integration versus continuous delivery versus continuous deployment

We will see that continuous integration captures the activities that can be automatically run once a change has been committed...
