This book explains how to take advantage of technologies like cloud, virtualization, and configuration automation to manage IT infrastructure using tools and practices from software development. These technologies have decoupled infrastructure from the underlying hardware, turning it into data and code. "Infrastructure as Code" has emerged alongside the DevOps movement as a label for approaches that merge concepts like source control systems, Test Driven Development (TDD) and Continuous Integration (CI) with infrastructure management.
Virtualization and cloud make it easy to rapidly expand the size of infrastructure, but the habits and practices we used in the past with hardware-based infrastructure don't keep up. Teams end up with hundreds of servers, all a bit different, and find themselves unable to fully automate their infrastructure.
The book will go through the challenges and problems created by all these wonderful new tools, and the principles and mindset changes that a team needs to make to use them effectively. It describes patterns, practices, and ideas that have been adopted from software development, especially Agile concepts, and brought into the IT Ops world as part of the DevOps movement. These ways of working have been proven in many organizations, including well known names like Netflix, Amazon, and Etsy, and also in more established organizations including publishers, banks, and even the British government.More info →
Learning Agile is a comprehensive guide to the most popular agile methods, written in a light and engaging style that makes it easy for you to learn.
Agile has revolutionized the way teams approach software development, but with dozens of agile methodologies to choose from, the decision to "go agile" can be tricky. This practical book helps you sort it out, first by grounding you in agile's underlying principles, then by describing four specific--and well-used--agile methods: Scrum, extreme programming (XP), Lean, and Kanban.
Each method focuses on a different area of development, but they all aim to change your team's mindset--from individuals who simply follow a plan to a cohesive group that makes decisions together. Whether you're considering agile for the first time, or trying it again, you'll learn how to choose a method that best fits your team and your company.
