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.

Adding Persistence

In this chapter, we will learn how to persist data that a microservice is using. As already mentioned in Chapter 2, Introduction to Spring Boot, we will use the Spring Data project to persist data to MongoDB and MySQL databases. The project and recommendation microservices will use Spring Data for MongoDB and the review microservice will use Spring Data for the JPA (short for the Java Persistence API) to access a MySQL database. We will add operations to the RESTful APIs to be able to create and delete data in the databases. The existing APIs for reading data will be updated to access the databases. We will run the databases as Docker containers, managed by Docker Compose, that is, in the same way as we run our microservices.

The following topics will be covered in this chapter:
