A must have guide to life!
Format: Hardcover
This was an amazing book! Transformative! It is not a quick read but a manual to really learning to let things go and how to truly be free! I find myself studying it , rereading, contemplating the words, doing the exercises, applying them. You can’t change if you don’t put in the work. This book has really taught me that!

This is a "Go-To" for thinking about Cloud Challenges.
Format: Paperback
Delivering and managing fully realized applications in the cloud is different. Different approaches to classic engineering problems than traditional On Premise development and different ways of thinking through the problems of "always available" solutions.
I've been in the software delivery business a long time, and with the cloud emerging, for good and ill: I understand the problems, but may be just a little set in my ways. I find this book helps me re-frame challenges in a way that aligns with the strengths of cloud computing. Solve the same problems faster, by thinking about them differently.
I'm finding "97 Things Every Cloud Engineer Should Know" great for re-centering my expectations about Cloud Native development and deployment of assets. I started reading it cover to cover over the Christmas Holiday but now i just pick it up and look for the group of essays about exactly the problem I'm wrestling with.
P.S. I'm heartened by the editors commitment to Black Lives Matter and Rule of Law. Mentioned only to balance the concerns from another review.
