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.

Questions

  1. What is required to turn a Spring Boot application created with Spring Initializr into a fully-fledged Netflix Eureka Server?
  2. What is required to make a Spring Boot-based microservice register itself automatically as a startup with Netflix Eureka?
  3. What is required to make it possible for a Spring Boot-based microservice to call another microservice that is registered in a Netflix Eureka server?
  4. Let's assume that you have a Netflix Eureka server up and running, along with one instance of microservice A and two instances of microservice B. All microservice instances register themselves with the Netflix Eureka server. Microservice A makes HTTP requests to microservice B based on the information it gets from the Eureka server. What will happen if, in turn, the following happens:
    • The Netflix Eureka server crashes
    • One of the instances of microservice...
