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.

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.
