Building Microservices with Micronaut (R)

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-time dependency injections and aspect-oriented programming
• Build cloud-native applications easily with the Micronaut framework

Book Description:

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.

What You Will Learn:

• Understand why the Micronaut framework is best suited for building microservices
• Build web endpoints and services in the Micronaut framework
• Safeguard microservices using Session, JWT, and OAuth in Micronaut projects
• Get to grips with event-driven architecture in Micronaut applications
• Discover how to automate testing at various levels using built-in tools and testing frameworks
• Deploy your microservices to containers and cloud platforms
• Become well-versed with distributed logging, tracing, and monitoring in Micronaut projects
• Get hands-on with the IoT using Alexa and the Micronaut framework

Who this book is for:

This book is for developers who have been building microservices on traditional frameworks such as Spring Boot and are looking for a faster alternative. Intermediate-level knowledge of Java programming and implementing web services development in Java is required.
