FinOps is a novel cloud operating model that uses interdisciplinary teams to manage cloud expenditures in concert. With the help of the tools, best practices, and culture introduced in this book, businesses can analyze cloud expenses and make strategic decisions in a better way. The book's ultimate objective is to teach companies how to establish a reasonable cost, speed, and quality balance in the cloud. The book begins with an overview of why FinOps exists, the problems it solves, the principles it is based on, and how it fits into the history of financial management. The subsequent chapters of this book explain the three stages—inform, optimize, and operate—and the best methods to use in each stage. The book then explains in depth, with examples, how to maximize efficiency while minimizing expenses for each of the three major public cloud providers: Google, Amazon, and Microsoft. The book also covers cost optimization techniques for the public cloud, FinOps operations management, cloud cost visibility, and forecasting.
