Summary

In this chapter, we began our journey into microservices by exploring their evolution and some useful design patterns. We covered the Micronaut framework in contrast to the traditional reflection-based Java frameworks. Essentially, Micronaut's approach to leverage ahead-of-time compilation (and not reflections) sets it apart as an ideal framework for developing microservices. To get our hands dirty, we went through setting up the Micronaut CLI on mac OS as well as Windows OS. Lastly, we worked on hello-world-maven and hello-world-gradle projects. In both projects, we added hello endpoints.

With the fundamentals of microservices as well as practical hello world projects covered, this chapter enhanced your knowledge of the evolution of microservices, their design patterns, and why Micronaut should be preferred for developing microservices. This foundational understanding is the bedrock for starting the adventure of microservices development in the Micronaut framework.

At the end of this chapter, we kickstarted an exciting journey into microservices development using the Micronaut CLI and Micronaut Launch. In the next chapter, we will explore how we can integrate different kinds of persistent storage and databases in the Micronaut framework.
