RabbitMQ use in Hub and Interact

The queues referred to in this topic relate to RabbitMQ queues and not to Blue Prism work queues.

The Blue Prism Hub platform uses quorum queues in RabbitMQ, which enable the use of high availability environments. Classic queues are not supported in these types of environments. For more information, see the RabbitMQ documentation on quorum queues.

The following diagram and table illustrate where RabbitMQ® is used in Blue Prism Hub and Interact.
