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.

Implementing a Microservice

This chapter takes you from the design stage to the implementation of our sample project—an online table reservation system (OTRS). Here, you will use the same design we explained in the last chapter and enhance it to build microservices. By the end of this chapter, you will have not only learned how to implement the design, but also the different aspects of microservices—building, testing, packaging, and containerization. Although the focus is on building and implementing the restaurant microservices, you can use the same approach to build and implement other microservices that are used in the OTRS. Sample code available on GitHub provides all three services in this chapter—the restaurant service, the booking service, and the user service.

In this chapter, we will cover the following topics:

  • OTRS overview
  • Developing and implementing...
