Through these conversations and discussions, dozens of people have contributed to this book, not to mention all those whose blogs, articles, books, webinars, videos, meetings, and presentations I learned from. The key contributors include my fellow DevOps subject matter experts and technology thought leaders at IBM. These include (in alphabetical order by first name): ■ Al Wagner ■ David Ziskind ■ Albert Ho ■ Dibbe Edwards ■ Alex Abi Khaled ■ Eric Minick ■ Ana Lopez-Mancisidor ■ Erik Anderson ■ Andy Moynahan ■ Greg Wunderle ■ Ann Marie Somerville ■ Hayden Lindsey ■ Anshu Kak ■ Helen Dai ■ Anujay Bidla ■ Jagan Karuturi ■ Ava Hakim ■ James Pierce ■ Bala Rajaraman ■ Jeff Crume ■ Bernie Coyne ■ Jim Fieseler ■ Bill Higgins ■ Jim Moffitt ■ Bob Bogan ■ John Lanuti ■ Brian Naylor ■ John Wiegand ■ Chris Lazzaro ■ Kay Johnson ■ Chris Lucca ■ Kedar Walimbe ■ C.

Their stories from the trenches are the best sources of lessons learned. In many cases, they were at the other end of the conversations that led to the lessons learned and practices documented in this book. Because I met most of these people in a professional capacity as an IBM employee, I cannot list them all here. I will list the few who also co-presented at conferences, meetings, and webinars with me, or co-authored articles or blogs with me. They include the following (along with their current employers): ■ Alan Shimel, DevOps.com ■ Antony Morris, Monitise ■ Ben Chodroff, CloudOne Acknowledgments xiii ■ Brad Schick, Skytap ■ Carmen DeArdo, Nationwide Insurance ■ Chris Lepre, Wells Fargo ■ Gareth Evans, Monitise ■ James Governor, RedMonk ■ Jayne Groll, DevOps Institute ■ John Comas, NBCUniversal Media ■ John Kosco, Blue Agility ■ J.
