About

Serverless Workflow presents a vendor-neutral, open-source, and entirely community-driven ecosystem tailored for defining and executing DSL-based workflows in the realm of Serverless technology.

The Serverless Workflow DSL is a high-level language that reshapes the terrain of workflow creation, boasting a design that is ubiquitous, intuitive, imperative, and fluent.

Bid farewell to convoluted coding and platform dependencies—now, crafting powerful workflows is effortlessly within reach for everyone!

Key features:

Ecosystem

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

It encompasses a comprehensive suite of components and tools designed to facilitate the creation, management, and execution of serverless workflows.

  1. DSL (Domain Specific Language): The core of the ecosystem, defining the fundamental syntax and semantics of Serverless Workflow specifications.

  2. CTK (Conformance Test Kit): A set of Gherkin features utilized for both conformance testing and Behavior Driven Design (BDD), ensuring compliance and facilitating testing across implementations.

  3. SDKs (Software Development Kits): These enable developers to interact with serverless workflows in various programming languages, providing functionalities such as reading, writing, building, and validating workflows.

  4. Runtimes: Dedicated environments for executing workflows defined using the Serverless Workflow DSL, ensuring seamless deployment and operation within diverse runtime environments.

  5. Tooling: Additional utilities and resources tailored to enhance the development, debugging, and management of serverless workflows, streamlining the workflow lifecycle from creation to deployment and maintenance.

SDKs

The Serverless Workflow SDKs are essential tools designed to assist developers in consuming, parsing, validating, and testing their workflows utilizing the Serverless Workflow DSL.

These SDKs empower developers to seamlessly integrate serverless workflows into their applications, providing robust support for various programming languages. By offering comprehensive functionality, they streamline the development process and enhance workflow management.
