Is this like Celery + RabbitMQ but with a GUI? On a high-level it sounds like that, but could someone be so kind as to give an example use case of this? How is it different that it's not just described as a distributed task queue?
The main difference is that workflow has state and tasks can be very long running. Also workflow can react to external asynchronous events. Visibility into overall progress is also a very important feature. When using a queueing system it is hard to answer about the current state of the business process.
For example implementing service deployment to a public cloud usign Celery + RabbitMQ is very non trivial and error prone. It is a pretty streightforward Cadence workflow.
