Acknowledgments

Writing a book is time-consuming. We invested our time, and other people did as well. We think that time is the most valuable resource on Earth, and we want to honor every minute spent by the people who helped us with this book.

To all the readers who bought the first edition of our book: thanks so much for your trust and support. Watching you reading our book and working through the examples boosted our motivation. Also, we learned quite a bit from your feedback.

Next, we want to thank all the readers who bought the MEAP edition of this book. Thanks for overlooking the rough edges and focusing on learning about AWS instead. Your feedback helped us to polish the version of the book that you are now reading.

Thank you to all the people who posted comments in the Book Forum and who provided excellent feedback that improved the book.

In addition, thanks to all the reviewers of the second and first edition who provided detailed comments from the first to the last page. The reviewers for this second edition are Antonio Pessolano, Ariel Gamino, Christian Bridge-Harrington, Christof Marte, Eric Hammond, Gary Hubbart, Hazem Farahat, Jean-Pol Landrain, Jim Amrhein, John Guthrie, Jose San Leandro, Lynn Langit, Maciej Drozdzowski, Manoj Agarwal, Peeyush Maharshi, Philip Patterson, Ryan Burrows, Shaun Hickson, Terry Rickman, and Thorsten Höger.
