Advance Praise for D evOps for Digital Leaders
“Everyone on the DevOps journey wants to see how others solved similar
problems in different business contexts. This book does a great job in chroni-
cling how organizations have applied DevOps patterns and articulating the
fantastic value they’ve created.”
—Gene Kim, co-author of T he Phoenix Project and DevOps Handbook
“DevOps for Digital Leaders addresses an important gap in the literature, pre-
senting DevOps from a business and organizational perspective rather than
the more common technology and process angles. Aruna, Kieren, and Peter
have done a great job of assembling, presenting, and addressing the core chal-
lenges of a transition to DevOps. Not only do they look at the impact on the
“path to production” of testing, deployment, and operational support, but they
tackle the complex topic of API design and even present the ROI justification
for DevOps, citing Dr. Nicole Forsgren’s groundbreaking work with the State
of DevOps reports. This book should be required reading for technology
leaders wondering about the impact DevOps will have on their organization.”
—Dan North, DevOps and Continuous Delivery pioneer,
Principal at Dan North & Associates Ltd.
“If D evOps for Digital Leaders had existed several years ago when we started
on our DevOps journey, it would have made our transition significantly easier.
This book is an excellent resource for both experienced and new DevOps
practitioners—more than just a ‘how-to’, it provides valuable insights and
real-world examples to which everyone can relate.”
—Dana Edwards, CTO/EVP, MUFG Union Bank
“As DevOps has risen to the top of the mind with IT departments big and small,
new and old, there has been much written about the subject. Unfortunately,
too much of it has been about ‘what is DevOps’ or shrouded in almost a
Zen-like philosophy. What has been missing is the practical ‘why’ and ‘how
to’ for practitioners. What’s missing is a guide that will grow dog-eared and
highlighted, with real-world examples and advice that practitioners will carry
with them and go back to again and again. DevOps for Digital Leaders is that
book. If you are looking for real-world examples and guidance on turning your
organization into a high-performing IT operation, this is a must-have book for
your library.”
—Alan Shimel, Editor-in-Chief, DevOps.com
“DevOps is no longer just a concept. This book by Aruna, Kieran, and Peter
places DevOps squarely in the real world. It is a comprehensive guide to help
you discover the origins of DevOps, realize the challenges, and gain a practi-
cal understanding of where DevOps fits into your development program, IT
operations, and business. It’s a must-have book for the business side to truly
comprehend DevOps, but also a great read for the IT community to under-
stand how their work ultimately impacts the business. And most importantly,
the book is loaded with valuable, actionable tips to help you navigate your
DevOps journey.”
—Pete Goldin, Editor and Publisher, A PMdigest and DEVOPSdigest
I would like to dedicate my fi rst book to my mother,
Sampurnam Th yagarajan, who has always been my
inspiration, who stood by me every step of the way.
I am who I am today because of her unconditional
love and dedication. I love you Amma.
—Aruna
I dedicate this book to all the true IT believers and
practitioners. Only from your collective eff ort can
organizations build the generative DevOps culture
needed to shape success. You know who you are!
—Peter
I dedicate this book to those who work to make the
world a better place for future generations.
—Kieran

Foreword
As a software executive who’s worn many hats across sales, services, develop-
ment, support, operations, and even IT, I have a fairly unique perspective when
I talk to business leaders about their technology strategies. Though the name
DevOps didn’t exist until fairly recently, the need for partnership between
development and operations teams has always been around. Today DevOps
has shifted from an emerging movement to a critical component of most
enterprises’ digital transformation strategy. In other words, DevOps is moving
from the Kanban board to the board of directors.
While the idea behind this kind of collaboration is common sense, there are
definitely challenges to driving mainstream adoption for DevOps. In my con-
versations with C-suite executives, they invariably ask for two things: docu-
mented best practices and actual case studies that they can take to their
internal stakeholders.
That’s why this book is so relevant right now. It’s more than just theory or a
summary of the ideal DevOps toolchain; it’s a set of practical insights and bet-
ter practices that came about through many, many interviews and interactions
with frontline practitioners about what works and what doesn’t work in the
real world.
Aruna, Kieran, and Peter are career high tech marketers who shed light on
the cultural and technological challenges to driving adoption for a DevOps
philosophy across the software development lifecycle. With this book, they
were able to bring together solid, actionable advice for anyone beginning their
DevOps journey, including recommendations on how to measure success and
return on investment from a business standpoint.
The days of organizational silos are coming to an end. Communication, col-
laboration, and automation are blurring the lines between development, QA,
and IT Operations—and enterprises are embracing agile and DevOps prac-
tices to increase software release frequency while improving overall quality.
I hope that in reading this, you find ways to optimize your technology strategy,
investments, and business outcomes.
—Adam Elster, President of Global Field Operations, CA Technologies
