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.

Developing event-driven asynchronous services

In this section, we will learn how to develop event-driven and asynchronous versions of the create and delete services. The composite service will publish create and delete events on each core service topic and then return a OK response back to the caller without waiting for processing to take place in the core services. This is illustrated in the following diagram:

We will cover the following topics:

  • Configuring Spring Cloud Stream to handle challenges with messaging
  • Defining topics and events
  • Changes in Gradle build files
  • Publishing events in the composite service
  • Consuming events in the core services
