||
| ## Background | ||
|
|
||
| Serverless Workflow is a vendor-neutral, open-source, and fully community-driven ecosystem | ||
| for defining and running DSL-based workflows that target the serverless technology domain. | ||
|
|
||
| This project is composed of: | ||
|
|
||
| * [Specification](https://github.com/serverlessworkflow/specification/blob/main/specification.md) for defining DSL-based workflows. | ||
| * [Developer SDKs](https://github.com/serverlessworkflow/specification#sdks) that provide support for many programming languages. | ||
| * [Workflow runtimes](https://github.com/serverlessworkflow/specification#runtime) part of the project ecosystem, and support the execution of specification DSL. | ||
| * [Developer tooling](https://github.com/serverlessworkflow/specification#Tooling) support for writing DSL-based workflows. | ||
|
|
||
| Serverless Workflow was approved as a Cloud Native Sandbox level project on July 14, 2020. | ||
|
|
||
| * [TOC review PDF](https://github.com/serverlessworkflow/specification/blob/main/community/presentations/2020-4-15-toc-pres.pdf). | ||
| * [TOC sandbox proposal PR](https://github.com/cncf/toc/pull/376) | ||
|
|
||
| ## Alignment with Cloud Native | ||
|
|
||
| Serverless Workflow project falls under the [CNCF "App Definition and Development"](https://landscape.cncf.io/card-mode?category=app-definition-and-development&grouping=category) category. | ||
|
|
||
| Serverless Workflow is a member project of the [CNCF Serverless Working Group](https://github.com/cncf/wg-serverless). | ||
|
|
||
| Serverless Workflow includes [Synapse](https://github.com/serverlessworkflow/synapse), a Kubernetes-native runtime engine for executing workflows that follows the specification DSL definition. | ||
|
|
||
| In addition, Serverless Workflow provides support for several other open-source projects and specifications in the cloud-native | ||
| space: | ||
|
|
||
| * CloudEvents | ||
| * OpenAPI | ||
| * AsyncAPI | ||
| * GraphQL | ||
| * OData | ||
| * OAuth2 | ||
|
|
||
| ## Year in Review | ||
|
|
||
| This year was for stabilization and discussions around the upcoming 1.0 release. The ecosystem kept growing: | ||
|
|
||
| * Two new releases for the [sdk-java](https://github.com/serverlessworkflow/sdk-java/releases) | ||
| * One new release for the [sdk-typescript](https://github.com/serverlessworkflow/sdk-typescript/releases) | ||
| * Four new releses for the [sdk-go](https://github.com/serverlessworkflow/sdk-typescript/releases) | ||
| * Seven minor releases for the [sdk-net](https://github.com/serverlessworkflow/sdk-net/tags) | ||
| * Four minor releases for the [Synapse](https://github.com/serverlessworkflow/synapse/releases) runtime | ||
| * Added [sdk-python](https://github.com/serverlessworkflow/sdk-python), a Python SDK into our ecosystem | ||
|
|
||
| From the community perspective we also had a good year: | ||
|
|
||
| <!-- I couldn't get this number for Twitter | ||
| * Over 100 new followers on our [twitter channel](https://twitter.com/CNCFWorkflow). | ||
| --> | ||
| * Over 210 new stars on our [specification github repo](https://github.com/serverlessworkflow/specification). | ||
| * Over 200 people attending our project kiosk at KubeCon NA 2022 | ||
| * Presented in-person at KubeCon EU 2022 for more than 100 people. | ||
| * Over 200 people attending our project office hours at 2022 KubeCon EU. | ||
| * Over 50 people attending our project office hours at 2022 KubeCon China. | ||

|
|
||
| - **How has the project performed against its goals since the last review?** | ||
|
|
||
| This is our second annual review since becoming a Sandbox project. | ||
| This year we looked for stabilization of the specification by having more | ||
| discussions with current implementation project leaders to achieve a good | ||
| balance between the standards and production-level use cases. | ||
|
|
||
| We decided to grow slowly and now we are reaching to a point to fix most of | ||
| the open issues and discussions before releasing 0.9 version, and then the final | ||
| 1.0 by the end of the year. | ||
|
|
||
| One of the goals we achieved, was to set a new governance model to balance the | ||
| responsibilities amongst all the maintainers. | ||
|
|
||
| We had to do a little detour duo to the progress of projects implementing and using | ||
| the specification in many production-level use cases. | ||
|
|
||
| - **What are the current goals of the project?** | ||
|
|
||
| Specification [roadmap](https://github.com/serverlessworkflow/specification/tree/main/roadmap) and [progress tracker](https://github.com/orgs/serverlessworkflow/projects/1/views/2). | ||
|
|
||
| Our main goals for the project include: | ||
|
|
||
| - Release specification version 1.0 by late 2023 | ||
| - Create a specification TCK | ||
| - Add integrations with different workflow DSLs | ||
| - Improve our community tooling support | ||
|
|
||
| - **How can the CNCF help you achieve your upcoming goals?** | ||
|
|
||
| - Help us in promoting the project (Blogs, Twitter, KubeCon, etc) | ||
| - If feasible help our project via crowdfunding [here](https://crowdfunding.lfx.linuxfoundation.org/projects/serverless-workflow) | ||
| - Keep providing us with opportunities to have project office hours and talks at KubeCons | ||
|
|
||
| - **Do you think that your project meets the criteria for incubation?** | ||
|
|
||
| We believe we have made significant progress toward this goal and that the project is ready for incubation. | ||
| We would like however to release Serverless Workflow specification v1.0 before starting this process | ||
| (scheduled for late 2023). | ||
