DevOps Handbook. Gene Kim, Jez Humble, Patrick Debois, John Willis

It is no secret that there is a close interdependence between software development and use. This is what a number of practices, collectively known as DevOps, use, and aim to help organizations create and update software products and services faster and better. This methodology focuses on aligning software development and delivery with its use, and this task is usually solved by automating processes and standardizing development environments to ensure rapid release preparation.

The “DevOps Guide”, created by four respected specialists who stood at the origins of this methodology, will not only introduce the professional reader to the ideology and practice of this movement, but will also provide a lot of useful advice on organizational changes and closer cooperation between different types of employees, unification and automation of various processes, their faster and more frequent execution, system administration, automation of delivery processes, etc. In general, DevOps encompasses the entire software delivery process, making it more predictable and dynamic, reliable and efficient. This significantly reduces the time to market for software, improves product quality, reduces the number of failures and malfunctions, and reduces the time for making changes and fixing errors.

So it is not surprising that this approach has gained wide popularity among engineers and managers of the world's most progressive IT companies.
