DevOps Adoption Strategies: Principles, Processes, Tools, and Trends

Overview of this book

DevOps is a set of best practices enabling operations and development teams to work together to produce higher-quality work and, among other things, quicker releases. This book helps you to understand the fundamentals needed to get started with DevOps, and prepares you to start deploying technical tools confidently. You will start by learning the key steps for implementing successful DevOps transformations. The book will help you to understand how aspects of culture, people, and process are all connected, and that without any one of these elements DevOps is unlikely to be successful. As you make progress, you will discover how to measure and quantify the success of DevOps in your organization, along with exploring the pros and cons of the main tooling involved in DevOps. In the concluding chapters, you will learn about the latest trends in DevOps and find out how the tooling changes when you work with these specialties. By the end of this DevOps book, you will have gained a clear understanding of the connection between culture, people, and processes within DevOps, and learned why all three are critically important.

Embracing this shift-left mindset necessitates organizations bridging the gap that typically exists between development and security teams, to the point where many of the security processes are automated and handled by engineering teams.

The following diagram helps depict how security fits into the existing DevOps loop:

Historically, major software developers would release new versions of their applications every few months, if not years. This gave the code enough time to go through quality assurance and security testing, which was handled by separate specialized teams, either internal or externally contracted.

However, the last 10 years...
