Multiprocess architecture

Note

This architecture is currently the recommended way to deploy simpleflow in production.

If you’re not familiar with the 3 standard roles around an SWF setup, go read the previous section about Standalone architecture. In this setup, the 3 roles are potentially distributed on different machines:

A few notes about this schema:

• the workflow started role is generally behind a web app or an automated system depending on your use case ; it’s pretty uncommon to have workflows launched manually via the simpleflow command-line.
• the activity workers can be distributed on many nodes, possibly with autoscaling mechanisms.
• the deciders on the other hand are usually only installed on a few machines, and don’t need autoscaling.
