What message format does Eventarc use to deliver events?

Eventarc delivers events using the CloudEvents specification, which is a standardized format for event data. This format is designed to facilitate the interoperability of event-driven systems by providing a consistent way to describe event metadata and content.

By utilizing CloudEvents, Eventarc enables seamless integration with various services in the Google Cloud ecosystem and beyond. This ensures that events can be easily consumed by different services and applications, not only within Google Cloud but also within external systems that adhere to the CloudEvents specification.

The importance of using a standardized format like CloudEvents lies in its ability to enhance compatibility and facilitate the development of event-driven architectures. This standardization is advantageous because it reduces the complexity typically associated with integrating heterogeneous systems and services.

While some services might use proprietary formats or different messaging protocols, Eventarc's adherence to CloudEvents ensures better alignment with industry standards and promotes easier debugging, tracing, and management of event flows.
