# CloudEvents
|
||
|
|
|
||
|
|
**Name of project**: CloudEvents
|
||
|
|
|
||
|
|
**Description**:
|
||
|
|
|
||
|
|
Last year the CNCF TOC created the Serverless Working Group to investigate
|
||
|
|
the Serverless landscape. The outputs of the WG included:
|
||
|
|
- a [whitepaper](https://github.com/cncf/wg-serverless#whitepaper) that:
|
||
|
|
- defines Serverless and its terminology
|
||
|
|
- describes common use cases for the technology
|
||
|
|
- compares it with other Cloud Native technologies and \*aaS environments
|
||
|
|
- describes the common architecture of Serverless platforms
|
||
|
|
- a [landscape document](https://docs.google.com/spreadsheets/d/10rSQ8rMhYDgf_ib3n6kfzwEuoE88qr0amUPRxKbwVCk/edit#gid=0)
|
||
|
|
that lists well-known open-source and proprietary Serverless platforms
|
||
|
|
and tools
|
||
|
|
- a set of recommended next steps for the WG, as part of the whitepaper:
|
||
|
|
- encourage more Serverless technology vendors and open source developers
|
||
|
|
to join the CNCF
|
||
|
|
- foster an open ecosystem by establishing interoperable APIs, in particular
|
||
|
|
around: Events, Deployments and Workflows
|
||
|
|
- provide additional education as needed
|
||
|
|
|
||
|
|
One of the recommendations, interoperability around Events, was agreed to
|
||
|
|
by the TOC and the WG began to develop a new specification for how
|
||
|
|
Events that are transferred between an event producer and an event consumer
|
||
|
|
should be formalized. The purpose of this would be to better enable
|
||
|
|
interoperability between these components such that basic processing of
|
||
|
|
the events (such as routing) can be achieved without having to require
|
||
|
|
knowledge of the event's structure in advance, or without understanding
|
||
|
|
the application specific data of the event.
|
||
|
|
|
||
|
|
The work on this specification is currently being done within the
|
||
|
|
CNCF's Serverless Working Group, but with the release of our first
|
||
|
|
milestone (v0.1), it would make sense for this work to be more
|
||
|
|
formalized as a new sandbox project under the CNCF.
|
||
|
|
|
||
|
|
The goals/roadmap of the project include:
|
||
|
|
- moving the specification to v1.0. A baseline format for an Event
|
||
|
|
to enable broad adoption within the Cloud community, and in particular
|
||
|
|
for Serverless/FaaS implementations
|
||
|
|
- define protocol mappings for popular transports, such as HTTP
|
||
|
|
- define serialization mappings for popular formats, such as JSON
|
||
|
|
|
||
|
|
**Statement on alignment with CNCF mission**:
|
||
|
|
|
||
|
|
Being born out of the CNCF's Serverless Working Group, the CloudEvents
|
||
|
|
project (and its members) share the CNCF's goals of promoting Cloud Native
|
||
|
|
technologies, and offering choice to our consumers through an open
|
||
|
|
interoperability specification, as shown by the significant participation
|
||
|
|
from key industry companies.
|
||
|
|
|
||
|
|
We believe that the CNCF provides the proper home for this due to its
|
||
|
|
commitment to the promotion and development of open, vendor-neutral projects.
|
||
|
|
Additionally, the wide breadth of the CNCF members will provide the feedback
|
||
|
|
necessary to ensure the CloudEvents specification isn't too limited in its
|
||
|
|
scope and appeals to as many constituents of the cloud native community
|
||
|
|
as possible.

|
**External dependencie**: None
|
||
|
|
|
||
|
|
**Initial Maintainers**:
|
||
|
|
|
||
|
|
The CloudEvents group does not have "maintainers" that approve
|
||
|
|
Pull Requests (PRs) like traditional GitHub projects. Rather, the group
|
||
|
|
discusses/reviews PRs in the PRs themselves and then when consensus is reached
|
||
|
|
they are approved during our weekly calls. If concensus can not be reached
|
||
|
|
then a formal vote is taken.
|
||
|
|
|
||
|
|
Voting rights: each member company designates a "primary" and "alternate"
|
||
|
|
member whose attendance at the weekly calls is tracked. Any member company
|
||
|
|
that attends three out of the last four meetings (current meeting not included)
|
||
|
|
has voting rights.
|
||
|
|
|
||
|
|
We also have this
|
||
|
|
[GOVERNANCE](https://github.com/cloudevents/spec/blob/master/GOVERNANCE.md)
|
||
|
|
doc which explains the processes we follow.
|
||
|
|
|
||
|
|
**Infrastructure Requests**: None
|
||
|
|
|
||
|
|
**Communication Channels**:
|
||
|
|
|
||
|
|
Mailing list: CloudEvents uses the CNCF Serverless WG mailing list:
|
||
|
|
https://groups.google.com/forum/#!forum/cncf-wg-serverless but we may
|
||
|
|
move to our own dedicated mailing list when/if the Serverless WG starts
|
||
|
|
a second project.
|
||
|
|
|
||
|
|
Slack: There is a #cloudevents Slack channel under CNCF's Slack workspace.
|
||
|
|
|
||
|
|
We have weekly zoom calls (9am PT on Thursdays):

**Release Methodology and Mechanics**
|
||
|
|
|
||
|
|
CloudEvents has a set of milestones defined in its
|
||
|
|
[roadmap](https://github.com/cloudevents/spec/blob/master/roadmap.md)
|
||
|
|
document. Beyond what is defined there, the group will decide when
|
||
|
|
significate progress has been made to warrant a new release.
