Building Microservices with Micronaut®

By: Nirmal Singh, Zack Dawood

Overview of this book

The open source Micronaut® framework is a JVM-based toolkit designed to create microservices quickly and easily. This book will help full-stack and Java developers build modular, high-performing, and reactive microservice-based apps using the Micronaut framework. You'll start by building microservices and learning about the core components, such as ahead-of-time compilation, reflection-less dependency injection, and reactive baked-in HTTP clients and servers. Next, you will work on a real-time microservice application and learn how to integrate Micronaut projects with different kinds of relational and non-relational databases. You'll also learn how to employ different security mechanisms to safeguard your microservices and integrate microservices using event-driven architecture in the Apache Kafka ecosystem. As you advance, you'll get to grips with automated testing and popular testing tools. The book will help you understand how you can easily handle microservice concerns in Micronaut projects, such as service discovery, API documentation, distributed configuration management, fallbacks, and circuit breakers. Finally, you'll explore the deployment and maintenance aspects of microservices and get up to speed with the Internet of Things (IoT) using the Framework. By the end of this book, you'll be able to build, test, deploy, and maintain your own microservice apps using the framework.

Architecting enterprise microservices

Implementing enterprise microservices requires understanding and motivation from multiple stakeholders in the organization. You need to plan and analyze whether a microservice is the right fit for the problem at hand. If it is a fit, then you must design, develop, deploy, manage, and maintain the service.

Before you start using microservices, let's understand when not to use them. Ask yourself the following questions:

  • Does your team know about microservices?
  • Is your business mature enough to adopt microservices?
  • Do you have an Agile DevOps practice and infrastructure?
  • Do you have a scalable on-premises or cloud infrastructure?
  • Do you have support to use modern tools and technology?
  • Is your database ready to be decentralized?
  • Do you have support from all the stakeholders?

If your answer is yes to each of these questions, you can adapt and roll out microservices. The hardest part about rolling...
