Quarkus
Quarkus is a Kubernetes-native Java framework tailored for GraalVM and HotSpot, designed to create efficient, lightweight, and fast-starting applications. It optimizes Java for cloud and serverless environments by reducing memory usage and boot time, making it ideal for microservices and containerized deployments. The framework supports imperative and reactive programming models, integrating seamlessly with popular Java libraries and standards.
Developers should learn Quarkus when building cloud-native applications, microservices, or serverless functions in Java, as it significantly improves performance and resource efficiency compared to traditional Java frameworks. It is particularly useful in Kubernetes or Docker environments where fast startup and low memory footprint are critical, and for projects requiring modern features like reactive programming or integration with tools like Kafka or RESTEasy.
