Acknowledgments
First, I would like to thank my family—my mother Kim, father John,
stepfather Jim, stepmother Veronica, stepsister Elizabeth, mother-in-law
Kathy, father-in-law Kevin and my grandparents, Bill and Mary-Jo—for
their support in my writing of this book and in everything I pursue. I would
also like to thank the entire OpenShift Team at Red Hat. They are the
ones who've made OpenShift a reality and therefore made this book a
possibility. In particular, I'd like to thank those in the team who have been
invaluable mentors to me: Mike McGrath, Thomas Wiest, and Dan
McPherson. I want to thank a dear friend of mine, Kyle Derr, who has
been a technical mentor over the years and has helped me substantially
reach a place that has made this book a possibility. I would like to thank
the community members of #rhel on irc.freenode.net for the sanity
checking and the technical guidance that they have provided over the
years. I would also like to thank Rob Marti for hiring and mentoring me
while I was at Sam Houston State University, this was largely a catalyst
for what I didn't know at the time would become the career I could only
have hoped for. I would like to thank Thomas Cameron for being a
mentor, a motivator, and someone who provided guidance to my
endeavors that ultimately lead me to writing this book. Finally, I want to
thank my wife Amanda, the love of my life and primary source of
inspiration in everything I do, technical or otherwise. Without her support,
this book and many other wonderful occurrences in my life surely would
not have happened.
About the Reviewers
André Dietisheim was quite passionate about coding Assembly
Language on Commodore Amiga as a teenager. This fervor made him
contribute later to the Java open source community in general and the
Eclipse platform in particular.
Today, he works on JBoss Tools, the Eclipse-based tooling that Red Hat
Inc. provides. He has also worked with Red Hat Inc. and his current task
is to create Eclipse tooling and a Java client for OpenShift.
Daniel Kinon has been in the IT industry for 14 years and working with
computers for much longer. Coming up through the ranks of Systems
Administration, Daniel's passion has always been focused on automation
to meet the ever-growing demands that software puts on infrastructure.
Having experienced first hand the difficulties inherent in implementing
PaaS, the release of OpenShift was a welcomed addition to Daniel's IT
tool belt and proved extremely useful during his time working for Red Hat
Inc. as a Sr. Technical Account Manager. Today, Daniel is continuing to
explore the relationship between software demands and infrastructure
scalability as the DevOps Architect for MarketLive Inc., the leading
provider of omni-channel eCommerce technology and services. When
he's not at the office or tinkering with Linux, Danielis a husband, father,
electronics hobbyist, and home brewer.
I've never seen proof of anyone succeeding on their own; I've always
been baffled by those who would want to. I'd like to thank my family
and mentors for always believing in me, and helping me to shape and
hone my ideas and opinions, making me who I am today. And a
special thank you to my wife and daughter for their support,
inspiration, and smiles.
