Nirvana provides the ability
to create clusters of realms that share channels and queues
within the namespace. Cluster objects can be created,
deleted and accessed programatically or throough the Nirvana
Administration Tool.
Objects such as channels or queues created within
a cluster can be accessed from any of the realms within
the cluster and Nirvana ensures that the state of each
objects is maintained by all realms within a cluster.
The clustering technology used within Nirvana ensures
an unsurpassed level of reliability, resilliance, scalability.
