   Modern JVM Framework
   ❖ Micronaut was designed from scratch in 2017, focused on modern
   architectures like microservices and serverless, with the cloud in
   mind.
   6
   All application types
   ❖ Micronaut is a complete solution for any type of application:
   microservices, message-driven producers or consumers, command-
   line apps, serverless functions
   Highly optimized
   ❖ Micronaut leverages Java annotation processors and other
   optimizations to compute the framework infrastructure at compile-
   time, drastically reducing startup time and memory consumption.
