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


Consistency

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

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

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


Serverless Workflow is a specification for describing workflows in a common way. It provides a vendor-neutral and platform-independent markup for orchestrating services on multiple runtimes and cloud/container platforms.

Serverless Workflow is a new effort and it's still under active development. Its working group consists of a number of leaders in the business automation industry and enthusiasts in that field.

The Serverless Workflow specification is a CNCF Cloud Native Sandbox level project.




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:



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
