Why this book? Throughout the year we spend a great deal of time studying, testing, fixing (and breaking) stuff, helping customers, colleagues, attending conferences, webinars, and so on. It would be a waste to keep it all to ourselves, right? After a period of 3 months, we received a total number of 152 submissions from all over the globe (20 countries), which we think is truly awesome. All together 140 people contributed. Byte-Sized is our (small) way of giving back, in the form of Cloud related design principles, architectural recommendations, tips, tricks, best and/or common practices, (funny) quotes, you name it. Hopefully, everyone who picked up a copy, either paperback or digital will take something useful away from it in their journey to the Cloud. All the best, Christiaan Brinkhoff and Bas van Kaam
