This book is great for those coming from Monolithic architectures (pretty much everyone, originally) and baby-stepping through the reasons why you may want to move services to a more micro level. It is definitely written from a pro-microservices standpoint, but refrains from being preachy.
Event-driven architectures are likely going to drive the future of architecture design, at least in the intermediate term. Centralizing has advantages, and this book dives deep into them.
If you have a keen interest in Software Architecture, it's nice to have a dictionary.
I read this when trying to get my hands on as much Architecture knowledge as was available. I'd prioritize this lower on the list than most, but its a decent read.
The CDK is a massive timesaver over raw Cloudformation, but even with helpful constructs in place, it takes some getting used to. Reading this book, while taking a few hours, will likely save you more than a few days over the course of time.
