Of the core 17 chapters of the book (Chapters 5-21), 12 of them end with instructions on how to deploy them in Vapor Cloud. From what I understand, we can learn about Heroku/AWS/Docker from the relevant chapters at the end only (Ch 32-34).
I am requesting the team to replace the current Vapor Cloud hand-holding in the above mentioned (5-21) chapters with one of the 3 other services.
Most of us who purchased this book, I presume, are beginners or have very little experience with server-side programming and setting up these 3 services. Without the hand-holding, it would be very difficult for us to derive the relevant steps for Heroku/AWS/Docker from their dedicated chapters at the end. We would be very likely to get stuck repeatedly without explicit instructions, rendering the purchase of this book of little value.
I understand that this is not a trivial task, but I ask you to consider this: 2-3 experienced people (who happen to have MADE the product!!!) working hard once, or thousands of complete novice readers, grappling in the dark, trying to find their way.
