kumuluz - Lightweight open-source framework for developing microservices using standard Java EE technologies and migrating Java EE to cloud-native architecture

KumuluzEE is a lightweight framework for developing microservices using standard Java/JavaEE/JakartaEE/EE4J technologies, extending them with Node.js, Go and other languages, and migrating existing applications to microservices and cloud-native architecture. KumuluzEE packages microservices as standalone JARs. KumuluzEE microservices are lightweight and optimized for size and start-up time. They fit perfectly with Docker containers. KumuluzEE microservices are fully compatible with Kubernetes.

KumuluzEE also provides extensions for developing common patterns in cloud-native architectures, including configuration, logging, discovery, fault tolerance with circuit-breakers, metrics, security, event streaming and more.
