What I’ve always tried to do is to cut through the hype, and help companies decide if microservices are right for them.

What You Will Learn

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 ...
