Cisco Intelligent Automation for Cloud 4.3.1 utilizes RabbitMQ
TM
technologies (
) as its broker.
This is a system whereby messages are published to a queue (or “buffer”) and what is known as a “Consumer” pulls
each message one at a time off a queue. Cisco IAC uses the “Publish/Subscribe” model in RabbitMQ.
each message one at a time off a queue. Cisco IAC uses the “Publish/Subscribe” model in RabbitMQ.
The Publisher (also called the “Producer”) in this scenario is Cisco Prime Service Catalog.
The Consumer is any Cisco Process Orchestrator environment (as many as needed).
In between the Publisher and the Consumer are:
—
The Exchange (for interpreting the XML message)
—
The Queue (for distribution)
Note
: Prime Service Catalog and Process Orchestrator must be installed, configured, and running.
Note
: RabbitMQ must be installed, configured, and running via the Prime Service Catalog Appliance. Queues and
Exchanges must also be configured and running. These have been pre-defined and set up by Cisco and are set in motion
via Cisco Prime Service Catalog. For more information on configuration document see
