Mastering Microservices with Java - Third Edition

By: Sourabh Sharma

Overview of this book

Microservices are key to designing scalable, easy-to-maintain applications. This latest edition of Mastering Microservices with Java, works on Java 11. It covers a wide range of exciting new developments in the world of microservices, including microservices patterns, interprocess communication with gRPC, and service orchestration. This book will help you understand how to implement microservice-based systems from scratch. You'll start off by understanding the core concepts and framework, before focusing on the high-level design of large software projects. You'll then use Spring Security to secure microservices and test them effectively using REST Java clients and other tools. You will also gain experience of using the Netflix OSS suite, comprising the API Gateway, service discovery and registration, and Circuit Breaker. Additionally, you'll be introduced to the best patterns, practices, and common principles of microservice design that will help you to understand how to troubleshoot and debug the issues faced during development. By the end of this book, you'll have learned how to build smaller, lighter, and faster services that can be implemented easily in a production environment.

Microservice Patterns - Part 1

This chapter takes you from the implementation of our sample project—an online table reservation system (OTRS)—to the next stage. In this chapter, we'll implement two important patterns that constitute the backbone of microservice-based systems—service discovery and registration, and a centralized configuration server. We'll learn more about the other important service patterns in the next chapter.

In this chapter, we will cover the following topics:

  • Service discovery and registration
  • Centralized configuration
  • The execution and testing of our containerized OTRS application

We'll continue adding to the code from our previous chapters. You can copy the last chapter's code and start following this chapter, or alternatively refer to the code that's available on GitHub or Packt's website.
