Beyond CloudEvents: Endpoints, Messages, Schemas – CNCF XRegistry - Manuel Ottlik, HDI Global SE
Manuel Ottlik, HDI Global SE
KubeCon + CloudNativeCon Europe 2025 · Session
This talk, presented by Manuel Ottlik of HDI Global SE, delves into the evolution of event-driven architecture tooling within the CNCF ecosystem, specifically focusing on **CloudEvents** and the newer **XRegistry** project. While CloudEvents successfully standardized the metadata for events, enabling interoperability across diverse messaging systems, it left a critical gap: the discovery and management of *what* events exist, *what* their payloads look like, and *where* they can be sent or received. XRegistry emerged to fill this void, providing a vendor-agnostic, extensible framework for managing metadata about *any* resource, with a particular focus on event-driven architecture entities like messages, schemas, and endpoints.

This session by Manuel Ottlik, a maintainer of both CloudEvents and XRegistry, addresses a critical and often overlooked gap in event-driven architectures: the comprehensive management of event definitions, schemas, and endpoints. While CloudEvents effectively standardized event metadata, XRegistry introduces a novel, extensible framework for bringing order and discoverability to the entire lifecycle of event assets. Its abstract `groups -> resources -> versions` model provides a vendor-agnostic foundation for enterprise-wide governance, offering significant practical impact for platform…
