Media Review

　　Ansible is the most popular automated operation and maintenance tool in the industry today. Unlike DevOps tools such as puppet, Ansible's no-client deployment model greatly reduces the user threshold, and its excellent design without sacrificing the architectural advantages of piping orchestration. The content of this book is easy to understand, convenient for readers to master, and quickly applied to their own real environment. Along with the chapters of this book, readers can gradually grasp the large-scale environment of the automated operation and maintenance capabilities, truly become a devops surfers.
--Journal of Easy product director, former Weibo system architecture Shirachen Lynn
One of the authors of this book is enthusiastic about the operation and maintenance of the cause, is the early operation of the automation initiator, the elder brother Yun Technology, the regular attention accumulation, blog articles are widely circulated. has been looking forward to ansible related books, this book will become a classic in the field of operations.
--Sohu Social products Center Python service Head Zhang Bin
With the elder brother has long been acquainted with, for many years he has been focused on automated operation and maintenance of research, and long-term struggle in the domestic well-known internet companies, accumulated a wealth of experience. This book is a brother and a great effort, is also a domestic engineer to write the first ansible books, is full of thousands of goods, it is worth studying carefully.
