CloudEvents

I’ve been recently talking about CloudEvents and AsyncAPI,two of my favorite open-source specifications for event-driven architectures. In this blog post, I want to talk about how you can use CloudEvents and AsyncAPI together. More specifically, I’ll show you how to document CloudEvents enabled services using AsyncAPI, thanks to the flexibility and openness of both projects.

Recap: CloudEvents and AsyncAPI

Let’s first do a quick recap CloudEvents and AsyncAPI.

I talked about CloudEvents in the context of event-driven architectures before. In this post, let’s explore CloudEvents in more depth.

CloudEvents: Why? What?

CloudEvents is a popular specification for describing event data in a common way with the goal of increasing interoperability between different event systems.

Google Cloud’s Eventarc, open-source Knative, Azure’s Event Grid, and many more projects rely on CloudEvent specification to define their event formats.
