Quarkus is a full-stack, open-source Java framework launched in 2019 by Red Hat. Quarkus is an alternative to Spring (although it can also be integrated with Spring), with some interesting features all to itself.
Quarkus is designed from the ground up to be “cloud-native,” meaning it’s tuned for Kubernetes, serverless platforms, and a variety of libraries like Apache Kafka (for stream processing) and JAX-RS (for RESTful web services). Quarkus also sports a full CDI (contexts and dependency injection) engine and Reactive programming support.
Read on for a hands-on introduction to Quarkus.
