The Micronaut open source software is a JVM-based framework, designed to create microservices quickly and easily.

Explore different aspects of building modular microservices such as development, testing, maintenance, and deployment using the Micronaut framework

Key Features

Learn how to build scalable, fast, and resilient microservices with this concise guide

Explore the many advantages of using reflection-free, compile- dependency injections and aspect-oriented programming

Build cloud-native applications easily with the Micronaut framework

Book Description

This book will help full-stack and Java developers to build modular, high-perfog, and reactive microservice-based apps using Micronaut.

You'll start by building microservices and learning about the core components of Micronaut, such as ahead-of- compilation, reflection-less dependency injection, and reactive baked-in HTTP clients and servers. Next, you will work on a real- microservice application and learn how to integrate Micronaut 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 the Micronaut framework, 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 Micronaut.

By the end of this book, you'll be able to build, test, deploy, and maintain your own microservice apps using Micronaut.
