Serverless Workflow

A specification for defining declarative workflow models that orchestrate event-driven, serverless applications.

Why Serverless Workflow

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.

What is Serverless Workflow

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.

Serverless Workflow Team Meeting Calendar

The Serverless Workflow Team meets biweekly, every second Monday at 10AM PT (USA Pacific) via Zoom.

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

Contribute to the Serverless Workflow Specification

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
