This book, like all good things, has come to an end. As pointed out numerous times, we've covered quite a lot in these pages. This book is by no means the definitive opus for adopting CD and DevOps; it is a collection of suggestions laid out in a logical order based on real-world experience and war stories. I recommend you put some effort into fleshing out your knowledge with other reading materials and books, or even attending a conference or two.
Even if you are simply window-shopping and looking at what is needed to implement and adopt CD and DevOps ways of working, you should now have a clearer idea of what you are getting yourself and your organization into. Forewarned is forearmed, as they say. It's not an easy journey, but it is worth it.
So, go grab yourself a hot beverage, a notepad, and a pen; skip back to Chapter 2, Understanding Your Current Pain...
