Events are everywhere. However, event publishers tend to describe events differently.
The lack of a common way of describing events means developers must constantly re-learn how to receive events. This also limits the potential for libraries, tooling and infrastructure to aide the delivery of event data across environments, like SDKs, event routers or tracing systems. The portability and productivity we can achieve from event data is hindered overall.
Enter CloudEvents, a specification for describing event data in a common way. CloudEvents seeks to ease event declaration and delivery across services, platforms and beyond.
CloudEvents is a new effort and it's still under active development. However, its working group has received a surprising amount of industry interest, ranging from major cloud providers to popular SaaS companies. Our end goal is to offer this specification to the Cloud Native Computing Foundation.
The following specifications are available:
| Latest Release | Working Draft | |
|---|---|---|
| CloudEvents | v0.1 | master |
| HTTP Transport Binding | v0.1 | master |
| JSON Event Format | v0.1 | master |
There is also the CloudEvents Extension Attributes document.
Learn more about the people and organizations who are creating a dynamic cloud native ecosystem by making our systems interopable with CloudEvents.
- Contributors: people and organizations who helped us get started or are actively working on the CloudEvents specification.
- Coming soon: demos & open source -- if you have something to share about your use of CloudEvents, please submit a PR!
The CNCF Serverless WG is working to formalize the specification based on design goals which focus on interoperability between systems which generate and respond to events.
In order to achieve these goals, the Serverless WG must describe:
- Common attributes of an event that facilitate interoperability
- One or more common architectures that are in active use today or planned to be built by WG members
- How events are transported from producer to consumer via at least one protocol
- Identify and resolve whatever else is needed for interoperability
We have google group for e-mail communications: cncf-wg-serverless
And a #cloudevents Slack channel under CNCF's Slack workspace.
See the CNCF public events calendar. This specification is being developed by the CNCF Serverless Working Group. This working group meets every Thursday at 9AM PT (USA Pacific):
