Spring 5.0 Microservices - Second Edition

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework’s core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring that focuses on Reactive Programming, you’ll be able to build modern, internet-scale Java applications in no time. The book starts off with guidelines to implement responsive microservices at scale. Next, you will understand how Spring Boot is used to deploy serverless autonomous services by removing the need to have a heavyweight application server. Later, you’ll learn how to go further by deploying your microservices to Docker and managing them with Mesos. By the end of the book, you will have gained more clarity on the implementation of microservices using Spring Framework and will be able to use them in internet-scale deployments through real-world examples.

Scaling microservices


At the end of Chapter 7, Scale Microservices with Spring Cloud Components, we discussed two options for scaling either using Spring Cloud components or dockerized microservices using Mesos and Marathon. In Chapter 7, Scale Microservices with Spring Cloud Components, you learned how to scale the Spring Boot microservices using the Spring Cloud components.

The two key concepts of Spring Cloud that we have implemented are self-registration and self-discovery. These two capabilities enable automated microservices deployments. With self-registration, microservices can automatically advertise the service availability by registering service metadata to a central service registry as soon as the instances are ready to accept traffic. Once microservices are registered, consumers can consume newly registered services from the very next moment by discovering service instances using the registry service. In this model, registry is at the heart of this automation.
