Infrastructure as Code


Book Description

Virtualization, cloud, containers, server automation, and software-defined networking are meant to simplify IT operations. But many organizations adopting these technologies have found that it only leads to a faster-growing sprawl of unmanageable systems. This is where infrastructure as code can help. With this practical guide, author Kief Morris of ThoughtWorks shows you how to effectively use principles, practices, and patterns pioneered through the DevOps movement to manage cloud age infrastructure. Ideal for system administrators, infrastructure engineers, team leads, and architects, this book demonstrates various tools, techniques, and patterns you can use to implement infrastructure as code. In three parts, you’ll learn about the platforms and tooling involved in creating and configuring infrastructure elements, patterns for using these tools, and practices for making infrastructure as code work in your environment. Examine the pitfalls that organizations fall into when adopting the new generation of infrastructure technologies Understand the capabilities and service models of dynamic infrastructure platforms Learn about tools that provide, provision, and configure core infrastructure resources Explore services and tools for managing a dynamic infrastructure Learn specific patterns and practices for provisioning servers, building server templates, and updating running servers

Promise Theory


Book Description

Promise Theory bridges the worlds of semantics and dynamics to describe scalable interactions between autonomous agents that form clusters and groups. It provides a broadly developed and semi-formal language, which builds on the mathematics of sets and graphs, and models intent and outcome in an impartial manner. The result is a theory that expresses a `chemistry' of cooperative behaviours for a wide range of systems, emphasizing how each new scale of cooperation leads to new phenomena and new promises.This book is aimed at scientists, philosophers, and engineers. It introduces readers to the key concepts in a practical manner, building on the foundation of voluntary cooperation as a ground state for all interacting systems. The book draws on many examples from the real world, with a particular emphasis on human-computer systems. `Promise Theory offers a methodology for generating certainty on top of uncertain foundations. This book presents the formal foundations of Promise Theory. It lays out the formalisms in a clear, concise, understandable way that makes them accessible to non-mathematicians. If you want to fully understand the conceptual mechanisms that underlie the distributed systems that make up today's "cloud services", you should start with this book.' -- Jeff Sussna, Author of Designing Delivery `[The authors] bring the rigor of theoretical physics to the science of cooperation. The application of this kind of rigor to the social sciences is a tremendous leap forward. [The] pioneering work on developing an algebra of cooperation is an idea whose time has come. A promise is not a guarantee. That said: I promise you that examining this book will stimulate your thinking about cooperation and collaboration at scale. This book covers a lot of ground: promises, impositions, invitations, games, and the peculiar dynamics of authority and authorization. Those looking for a book that applies the lessons of distributed computing to the new and emerging science of cooperation will find what they are looking for here.' -- Daniel Mezick, Author of The Culture Game and Inviting Leadership
