Chapter 1: Getting Started with Microservices Using the Micronaut Framework
In recent times, there's been a good buzz about microservices and how the microservices architecture has been transformational in developing rapid, agile, and enterprise-grade web services to address the unique challenges and requirements of today's world. The microservices architecture has turned the page toward disciplining the standards on developing these web services. In this chapter, we will walk through the evolution of web services to microservices. We will quickly dive into some useful microservices design patterns. We will zero in on the key pitfalls in most of the traditional Java development frameworks and how their surface-level adoption to the microservices architecture has elevated performance and optimization issues. We will then explore how the Micronaut framework has addressed these performance and optimization issues in the microservices with an overhauled and ground-up approach to microservices development. Lastly, to get started with the Micronaut framework, we will set up the Micronaut CLI and work on a small hello world project.
In this chapter, we will focus on these topics in particular:
- Introducing microservices and their evolution
- Understanding microservices design patterns
- Why Micronaut is the best choice for developing microservices
- Getting started with the Micronaut framework
- Working on the hello world project in the Micronaut framework
By the end of this chapter, you will have an understanding of how web services evolved in to microservices and why traditional Java frameworks are ineffective for developing microservices as compared to the Micronaut framework. Furthermore, we will also gain the practical knowledge to start using the Micronaut framework by working on a small project in the Micronaut framework.
