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.

Architecting the solution

As the maintainer of a product’s architecture, the system architect keeps track of the capabilities of the product and enhances them through the creation of enablers and understands the constraints of the system as identified by NFRs.

Working with others on the ART or others in the organizations, the system architect will explore the following aspects of the product to ensure that NFRs are satisfied:

  • Releasability
  • Security
  • Testability
  • Operational needs

Let’s examine these aspects in further detail.

Architecting releasability

It is often desirable to release new features to the customer at the organization’s discretion. We still want a deployment to a production environment as part of the development cadence, but the actual release becomes a business decision. For this reason, we look to separate the deployment from the release.

Architecture may play a key role in allowing the separation of the deployment...
