This turned out to be a Good Thing™. While I'm often skeptical of book recommendations (what's meaningful to one person doesn't necessarily work for another person), I think Kim and his co-authors knocked it out of the park with The Phoenix Project, and managed to make a really convincing case that companies urgently need to embrace DevOps and provides a narrative as to how they'd do that.
What I find particularly valuable about The Phoenix Project is the way that the subject is approached. Rather than a dry business/tech tome that preaches the gospel of DevOps, The Phoenix Project provides an illustrative story of how DevOps solves real problems and transforms a business. While it's not great literature, it's an easy read that packs a lot of punch.
Kim also packs a lot into a short talk. We had the great pleasure of having Kim give a keynote at the CloudStack Collaboration Conference (as well as giving each attendee a copy of TPP), and he did a fantastic job of helping convince the audience about the need for DevOps.
(Side note: You'd think that folks using Apache CloudStack, or cloud in general, would also be employing DevOps tactics. Not so, at least according to Donnie Berkholz of RedMonk - who says that most crossover of DevOps and Cloud come from Bay Area startups without a lot of legacy to deal with...)...
