Helidon is a set of Java libraries for developing microservices. It includes Helidon SE for a reactive web server and Helidon MP which supports MicroProfile standards. The presentation provides an overview of Helidon's architecture and capabilities, including security, configuration, reactive routing, and integration with technologies like CDI, JAX-RS, and JSON processing. Future plans include improved support for HTTP/2, reactive clients, and tighter JDK integration.
