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.

Pipelines and toolchains

A toolchain is the set of tools used in DevOps practices in the product development life cycle. The classic representation of the toolchain used in DevOps is an infinity loop, broken up into a number of functions. Each function or stage is enhanced by automation. A representation of this infinity loop, created by Kharnagy, and licensed under the Creative Commons Attribution ShareAlike license, is shown in the following figure:

If we separate the ends of this infinity loop, we see the basis of our pipeline. The pipeline orchestrates the operation of all the stages with the exception of the monitoring stage. This begins our look at each pipeline stage, as shown in the following figure:

We begin our examination of the pipeline by looking at the activities whose artifacts set the pipeline in motion: plan and create. These foundational...
