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.

Learning from failure

Production failures can happen at any time in the product development process, from the first deployment to supporting a mature product. When these production failures happen, depending on the impact, they may adversely affect the value the customer sees and potentially ruin a business’s reputation.

Often, we don’t see the lessons offered by these production failures until the failures happen or afterward when reading about such failures happening to another organization (or even a competitor!).

We will examine a sample of such famous production failures, hoping to glean lessons through the benefit of hindsight. The following examples include the following:

  • The rollout of healthcare.gov in 2013
  • The Atlassian cloud outage in 2022

Other lessons will come from other sections in this chapter.

In 2010, the Patient Protection and Affordable Care Act became law in the USA. A key part of this law, colloquially...
