Learn Microservices with Spring Boot (2nd edition)

Learn Microservices with Spring Boot (2nd edition)

In 2017, I wrote the book Learn Microservices with Spring Boot. Initially, it was a self-published project. After a few weeks online, Apress contacted me to publish it as part of its catalog, and I was glad to work with them to make it a better version.

I got a lot of feedback since then, and some technologies used in the book have been updated. Besides, I learned new topics, and came up with better ideas for structuring the contents of a new book.

So I’m now working on a Second Edition of this book with some interesting new additions:

  • Spring Boot 2.3.
  • More in-detail explanation about how Spring Boot works.
  • Smoother learning curve.
  • More focus on Non-Functional Requirements, with Resilience and Scalability in practice.
  • All the Cloud-native patterns have been updated to use the new standards: Spring Cloud Gateway, Spring Cloud Load Balancer. For consistency, Service Discovery uses now Consul instead of Eureka.
  • The small UI app uses React instead of plain JavaScript.
  • … and more!

The book source code repositories are available online. Check them on Github.

The practical case study

All the contents in the book are presented around a practical case study, that evolves each chapter with the introduction of new concepts.

You start with a small monolith, looking at the best design practices, and you learn how Spring Boot works with real examples.

Then, you introduce a second microservice, and study the differences between synchronous and asynchronous communication. That’s how you get to Event-Driven architectures. Once you enter into the world of microservices, you must learn the most important architecture patterns for distributed systems: Gateway, Service Discovery, Load Balancing, Resilience, Scalability, Distributed Tracing, etc.
