This book explains the management aspects of DevOps for those who are professionally engaged in information and technology management. It is written for IT specialists, IT managers and IT executives. It does not show DevOps 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 DevOps 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 DevOps, 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 DevOps Foundation certification. This exam tests the understanding of basic DevOps concepts and how they relate to each other, as well as the value of DevOps for the business. EXIN DevOps Foundation is the first level of the EXIN DevOps certification program. The EXIN DevOps Professional certification tests the knowledge of DevOps practices and how to integrate teams. The EXIN DevOps Master certification is about promoting organizational change and leading the way towards continuous delivery and improvement.
