A Nirvana Realm is the name
given to a single Nirvana server. Nirvana realms can
support multiple network interfaces, each one supporting
different Nirvana protocols.
A Nirvana Realm can contain many channels, message
queues or peer 2 peer services.
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
progratically or throough the Nirvana Administration
Tool.
Objects 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.
Realms can also be added to one another within the
namespace. This allows the creation of a federated
namespace where realms may be in different physical
localtion, but accessible through one physical namespace.
