Hands-On Microservices with Spring Boot and Spring Cloud

By: Magnus Larsson

Overview of this book

Microservices architecture allows developers to build and maintain applications with ease, and enterprises are rapidly adopting it to build software using Spring Boot as their default framework. With this book, you’ll learn how to efficiently build and deploy microservices using Spring Boot. This microservices book will take you through tried and tested approaches to building distributed systems and implementing microservices architecture in your organization. Starting with a set of simple cooperating microservices developed using Spring Boot, you’ll learn how you can add functionalities such as persistence, make your microservices reactive, and describe their APIs using Swagger/OpenAPI. As you advance, you’ll understand how to add different services from Spring Cloud to your microservice system. The book also demonstrates how to deploy your microservices using Kubernetes and manage them with Istio for improved security and traffic management. Finally, you’ll explore centralized log management using the EFK stack and monitor microservices using Prometheus and Grafana. By the end of this book, you’ll be able to build microservices that are scalable and robust using Spring Boot and Spring Cloud.

Using Netflix Eureka as a discovery service

A discovery service is probably the most important support function required to make a landscape of cooperating microservices production-ready. As we already described in Chapter 1, Introduction to Microservices, in the Service discovery section, a discovery service can be used to keep track of existing microservices and their instances. The first discovery service that Spring Cloud supported was Netflix Eureka.

We will use this in Chapter 9, Adding Service Discovery Using Netflix Eureka and Ribbon, along with a load balancer and the new Spring Cloud load balancer.

We will see how easy it is to register microservices with Netflix Eureka when using Spring Cloud, and as a client sends HTTP requests such as a call to a RESTful API to one of the instances registered in Netflix Eureka. We will...
