Quarkus - Supersonic Subatomic Java
Quarkus is a Cloud Native, (Linux) Container First framework for writing Java applications.
* Container First:
Minimal footprint Java applications optimal for running in containers.
* Cloud Native:
Embraces 12 factor architecture in environments like Kubernetes.
* Versatile:
From the smallest microservice to the largest monolith.
* Fast startup:
We do more at build time, we start fast.
* JVM and native
JVM for high throughput, native for constrained environments.
* Unify imperative and reactive:
Brings under one programming model non-blocking and imperative styles of development.
