2. Background

Workflows have become key components of Serverless applications, yet implementations tend to describe workflows differently.


The lack of a common way of describing serverless workflows means developers do not have a consistent way of modelling their serverless orchestrations.

The portability and productivity we can achieve from modeling serverless workflows is hindered overall.

No common workflow format means no common libraries, tooling, and infrastructure for modeling serverless workflows across different cloud platforms and/or containers.

Serverless Workflow addresses the need for a community-driven, vendor-neutral and a platform-independent workflow language specification that targets the serverless computing technology domain.

Having and using a specification-based workflow language allows us to model our workflows once and deploy them onto many different container/cloud platforms, expecting the same execution results.

3. About

Serverless Workflow is based on well-established and known standards such as CloudEvents, OpenApi, and gRPC.

The specification includes multiple components:

4. Meetings

The Serverless Workflow Team meets weekly, every Monday at 10AM PT (USA Pacific) via Zoom.
Anyone is encouraged to join and collaborate. Please read our our Code of Conduct before joining the first time.

Below is the CNCF Public Events Calendar which includes all of the Serverless Workflow team meetings:

5. Contribute

Serverless Workflow is organized via the CNCF's Serverless Working Group.

It is hosted by the Cloud Native Computing Foundation (CNCF) and was approved as a Cloud Native Sandbox level project on July 14, 2020
