-Hybrid messaging deployment with qdrouterd server
--------------------------------------------------
-
-In OSA, the deployment of disparate messaging backends is completely
-transparent to the OpenStack services. By managing the inventories for
-the messaging servers, a hybrid messaging configuration will be created.
-The instantiation of the qdrouterd server role in the
-qdrouterd_host_group will automatically setup the oslomsg_rpc*
-variables to use this messaging backend. No additional configuration
-is required. The result is that RPC services will communicate via the
-amqp (V1.0 protocol) driver and the Notify services will communicate
-via the rabbit driver. The separation and use of different messaging
-backends can provide increased scale and resiliency.
