As mentioned above, the clients need to be able to find the location of the active virtualhost within the group.

Clients can do this using a static technique, for example , utilising the failover feature of the Apache Qpid JMS and Apache Qpid JMS AMQP 0-x clients where the client has a list of all the nodes, and tries each node in sequence until it discovers the node with the active virtualhost.

Another possibility is a dynamic technique utilising a proxy or Virtual IP (VIP). These require other software and/or hardware and are outside the scope of this document.
