Everyone talks about it, but not everyone knows what it is.
In broad terms, DevOps is an approach based on lean and agile principles in which business owners and the development, operations, and quality assurance departments collaborate to deliver software in a continuous manner that enables the business to more quickly seize market opportunities and reduce the time to include customer feedback. Indeed, enterprise applications are so diverse and composed of multiple technologies, databases, end-user devices, and so on, that only a DevOps approach will be successful when dealing with these complexities. Opinions differ on how to use it, however.
Some people say that DevOps is for practitioners only; others say that it revolves around the cloud. IBM takes a broad and holistic view and sees DevOps as a business-driven software delivery approach — an approach that takes a new or enhanced business capability from an idea all the way to production, providing business value to customers in an efficient manner and capturing feedback as customers engage with the capability. To do this, you need participation from stakeholders beyond just the development and operations teams. A true DevOps approach includes lines of business, practitioners, executives, partners, suppliers, and so on.This book takes a business-centric approach to DevOps. Today’s fast-moving world makes DevOps essential to all enterprises that must be agile and lean enough to respond rapidly to changes such as customer demands, market conditions, competitive pressures, or regulatory requirements.
If you’re reading this book, we assume that you’ve heard about DevOps but want to understand what it means and how your company can gain business benefits from it. This book is geared to executives, decision makers, and practitioners who are new to the field of DevOps, who seek more information about the approach, and who want to cut through the hype surrounding the concept to get to the meat of it.
