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.

Summary

Demystifying Microservices

Microservices is an architecture style and an approach for software development to satisfy modern business demands. Microservices are not invented, it is more of an evolution from the previous architecture styles.

We will start the chapter by taking a closer look at the evolution of microservices architecture from the traditional monolithic architectures. We will also examine the definition, concepts, and characteristics of microservices.

ByÂ the end of this chapter, you will have learned about the following:

Evolution of microservices
Definition of microservices architecture with examples
Concepts and characteristics of microservices architecture
