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.

We need to see that our features function as we expect. This is true from a functional perspective, but also from other perspectives relating to NFRs.

The following practices allow us to verify correct behavior in the production environment:

  • Production testing
  • Test automation in production
  • Test data management
  • Testing NFRs

Some of these practices were introduced in the previous chapter but now that we are looking at the production environment, we can examine them closely. Let’s look at all these practices and their application to production.

Production testing

With feature flags in place as part of a dark launch, testing can continue against the resources of the production environment. While testing in the production environment is no greater...
