Oracle has introduced Project Helidon, an open source microservices framework for Java.

Helidon features a collection of Java libraries for writing microservices that will run on a web core powered by the Netty network application framework. The project also includes Helidon Reactive WebServer, which provides a functional programming model to run on Netty. Cloud application development is supported, along with health checks, metrics, tracing, and fault tolerance.

Oracle said that although it is already possible to build Java EE (Enterprise Edition) microservices, it is better to have a framework designed for this purpose. The intent has been to build lightweight libraries that do not require an application server and can be used in Java SE (Standard Edition).
