I would like to thank my wife for giving the thumbs up to this book project, while just recovering from the previous book. It was a stretch goal, but with her support and the patience and love of the rest of my family, it became possible. I'm also grateful to the rainy winters we get in the Pacific Northwest as I didn't feel bad staying inside writing!

I would like to extend a special thanks to our early reviewers—without them, the book wouldn't be as great as it is now. I want to use this opportunity to give kudos to a bunch of first class software engineers and architects who have inspired me and from whom I've learned so much throughout my career: Romuald van der Raaij, André Weber, Philip Thomas, Pierre-Antoine Grégoire, Carl Schmidt, Tim Meighen, Josh Devins, Dominic Farr, Erik Garrett, and Ken Pratt.
