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.

Chapter 6. Microservices Evolution – A Case Study

Like SOA, a microservices architecture can be interpreted differently by different organizations, based on the problem in hand. Unless a sizable, real-world problem is examined in detail, the microservices concepts are hard to understand.

This chapter will introduce BrownField Airline (BF), a fictitious budget airline, and their journey from a monolithic Passenger Sales and Service (PSS) application to a next-generation microservices architecture. This chapter examines the PSS application in detail, and explains the challenges, approach, and transformation steps of a monolithic system to a microservices-based architecture, adhering to the principles and practices that were explained in the previous chapter.

The intention of this case study is to get us as close as possible to a live scenario so that the architecture concepts can be set in stone.

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

  • A real-world case for migrating...
