Open Source Equivalent of AWS Flow Framework [clos

Question

There many workflow system out there but I was wondering which one of the open source workflow management system is the closest to the AWS Flow Framework (with Amazon SWF like capability build in)?

Answer 1

(Shameless post?) I started writing my own library (SimpleWorkflowFramework.NET) for use in C# and its available at https://github.com/sdebnath/SimpleWorkflowFramework.NET. It definitely could use some help if anyone is interested.

Answer 2

AWS Flow Framework itself is open source under Apache 2.0 license. Its source code is available on github: https://github.com/aws/aws-swf-flow-library.

Update: At 2017 Uber released Cadence which is an open source version of SWF service and associated client side libraries.

Answer 3

Amazon SWF is quite different from the other existing workflow systems :

• It is not trying to implement BPMN (we could say it is lower level than most workflow systems)
• It is focused on distributing tasks to heterogeneous systems (so you can run the activities on any platform, in any language.)

Besides the official Java Flow Framework, I only know :

• Gordon (Ruby), but I'm not sure it's open-sourced yet
• aws-swf-toolkit (Javascript/Node.js) (disclaimer: I'm the author of this one)
