Designers can specify an at least once intent to require that
providers receive every message at least once.
Reliability intents usually apply at service
virtualization bindings. If you apply them to composites, service
virtualization bindings of the composite inherit them, as appropriate.

The provider must receive every message sent to it by
consumers at least once. It may receive some messages more than once.
If the node or the Message Bus fails, it must deliver
messages after it restarts. Messages must be persistent; if the provider cannot
successfully process a message, the Message Bus must re-deliver it after a
delay. The consumer must send every message using the persistent mode of the
Messaging Bus.
