DevOps – A Business Perspective [PDF ebook] 

This book explains the management aspects of Dev Ops for those who are professionally engaged in information and technology management.
It does not show Dev Ops as a phenomenon associated with new automation tools, programming techniques or technologies; It differs from other books by the structural nature of the narrative (perhaps, excessively structured) approach and by the attempt to cover fully the phenomenon of Dev Ops at a basic, fundamental level.
By this approach, this book not only creates awareness of the new subject area but is also helps building the basics. The reader learns about the origins of Dev Ops, the inevitability of its emergence, the key prerequisites and their reflection in practices, about the practices themselves and the principles on which they are based.
This book is the core literature of the EXIN Dev Ops Foundation certification. This exam tests the understanding of basic Dev Ops concepts and how they relate to each other, as well as the value of Dev Ops for the business. EXIN Dev Ops Foundation is the first level of the EXIN Dev Ops certification program. The EXIN Dev Ops Professional certification tests the knowledge of Dev Ops practices and how to integrate teams. The EXIN Dev Ops Master certification is about promoting organizational change and leading the way towards continuous delivery and improvement.
