This book is designed as a deep dive into how you think about, and execute, breaking
apart existing systems into a microservice architecture. We will touch on many topics
related to microservice architecture, but the focus is on the decomposition side of
things. For a more general guide to microservice architectures, my previous book
Building Microservices would be a good place to start. In fact, I strongly recommend that
you consider that book to be a companion to this one.
