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.

Summary

Automation plays a key role in DevOps. We looked at the important tools that make up a DevOps toolchain, especially those parts of the toolchain that are orchestrated from building and testing to deployment, creating the CI/CD pipeline or the pipeline.

CI typically includes activities that happen to code changes after they have been committed to version control. This may include preliminary testing, and upon passing, they may be built together and packaged into an artifact based on language and technology.

CD continues from where CI leaves off by taking the build artifacts and applying them to testing or production environments. Here, environments will be reconfigured, possibly with new resources. Additional testing will be performed to ensure security, correctness, and validation of anticipated value.

DevOps topologies outline possible models of collaboration between Dev and Ops teams with the possible inclusion of people specializing in DevOps. Some of the topologies...
