1. What is Micronaut
Micronaut is a JVM framework for building lightweight modular applications. It was developed by OCI, the same company that Grails gave us. Micronaut is a modern framework designed to make the creation of microservice applications quick and easy.
Micronaut contains features similar to existing frameworks such as Spring, but at the same time it implements some new ideas that are its distinctive features. Together with the support of Java, Groovy and Kotlin, it offers many ways to create applications.
