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

  1. Internet of Things (IoT) is a network of devices or things. These things could be anything from a human wearing a health monitor, a pet wearing a geolocation sensor, a car with a tire pressure sensor, a television with voice/visual capabilities, or a smart speaker.

    We discussed this in the Basics of IoT section.

  2. Doorbells, locks, lightbulbs, speakers, televisions, healthcare systems, fitness systems, Google Home, Amazon Alexa, Apple Siri, Microsoft Cortana, and Samsung Bixby.

    We discussed this in the Basics of IoT section.

  3. Alexa skills are like apps, and you can enable or disable skills using the Alexa app for a specific device. Skills are voice-based Alexa capabilities.

    We discussed this in the Basics of IoT section.

  4. Intents capture events the end user wants to implement with their voice. An intent represents an action that is triggered by the user's spoken request. Intents in Alexa are specified in a JSON structure called intent schema. Built-in intents...
