Overview of this book

Spring is one of the best frameworks on the market for developing web, enterprise, and cloud ready software. Spring Boot simplifies the building of complex software dramatically by reducing the amount of boilerplate code, and by providing production-ready features and a simple deployment model. This book will address the challenges related to power that come with Spring Boot's great configurability and flexibility. You will understand how Spring Boot configuration works under the hood, how to overwrite default configurations, and how to use advanced techniques to prepare Spring Boot applications to work in production. This book will also introduce readers to a relatively new topic in the Spring ecosystem – cloud native patterns, reactive programming, and applications. Get up to speed with microservices with Spring Boot and Spring Cloud. Each chapter aims to solve a specific problem or teach you a useful skillset. By the end of this book, you will be proficient in building and deploying your Spring Boot application.

Implementing Service Discovery – Eureka clients


Service Discovery is one of the key patterns of a microservice-based architecture. Spring Cloud provides Service Discovery functionality with Netflix OSS's Eureka. Eureka is the Cloud Service Discovery Server and Client. In the previous section, we saw how to implement the Netflix Service Discovery server. Here, I am going to implement the Netflix Service Discovery client.

Adding the Maven dependencies configuration

Also include spring-boot-starter-web in pom.xml and implement a REST controller to create a simple REST service to be registered with the Eureka Discovery Server. Let's see the following Maven configuration file:
