A composite resource is established that includes a plurality of members.
Each of the members is capable of providing a comparable service. A
coordinator monitors a state of each member of the composite resource. A
component requests the service from the coordinator. The coordinator
arranges for the service to be provided to the component by a particular
member of the composite resource. When the particular member ceases to be
active, the service is automatically provided to the component by another
member in the composite resource. A state of the composite resource is
maintained independently of the state of each member in the composite
resource.
