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.

Chapter 10: IoT with Micronaut

Internet of Things (IoT) is one of the fastest emerging technologies. It is a network of devices or things. These devices have the same capabilities as sensors or software and can communicate with other devices over the internet. A device or thing can be from various fields and can include things such as light bulbs, door locks, heartbeat monitors, location sensors, and many devices that can be enabled with sensors. It is an ecosystem of smart devices or things with internet capabilities. IoT is trending in various fields. A few of the top trending fields are as follows:

  • Home automation
  • Manufacturing and industrial applications
  • Healthcare and medical science
  • Military and defense
  • Automotive, transportation, and logistics

Along with these fields, in this chapter, we will learn about the following topics:

  • Basics of IoT
  • Working with Micronaut Alexa skills

By the end of this chapter, you will be well versed...
