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 deployment

During the continuous integration phase of the pipeline, we saw the last step as the packaging of changes into a binary image. Continuous deployment continues from that step to the application of that image into testing and production environments.

Automation may play a role in adding or updating resources in these environments. IaC tools allow the configuration of these resources.

Now that code changes are in an environment, testing can be done in further detail to find problems with quality and security. Here, the tests may also look at how changes affect the performance and validation of the desired changes.

As changes are added to environments, we need to be aware of the effects of these changes. To that end, we will measure the performance of the overall environment including the storage and analysis of logs.

The continuous deployment stage is illustrated in the following figure:
