DevOps For Dummies

Introduction

I believe that the greatest challenges facing the tech industry aren’t technical; they’re human. Think about it: Hardware and computing are more powerful than they ever have been. Automated tools remove the drudgery of rote work. Robust frameworks and libraries build shortcuts and functionality into applications for you. You can do more, faster, than ever before.

The problem that organizations face now is that of the social dynamics of humans on engineering teams. Specifically, those dynamics are the natural friction that arises from misaligned incentives and poorly communicated goals; the frustration in attempting to explain a concept or approach to someone who has a different expertise than you; and the fear people feel when they think about looking stupid in front of their colleagues or being automated out of a job.

DevOps addresses all these issues, and this book explains how.

About This Book

I’ve designed this book to be a resource that someone who has never heard of DevOps — or doesn’t know what it actually means — can walk through to gain a broad understanding of DevOps and how it fits into the software development life cycle (SDLC) — that is, the entire process of how software is developed and released. Although SDLC has traditionally used the word development, I prefer delivery because it removes the possible elevation of developers over other disciplines.

I’ve ordered the information in this book to be both approachable chronologically as well as selectively. ...
