org.rhq.core.domain.cloud.AffinityGroup
An object to logically group {@link Server}s and {@link Agent}s together so that the high-availability distribution algorithm repartitions the {@link Agent}s with tendencies to connect and fail over to {@link Server}s in the same {@link AffinityGroup}. @author Joseph Marques
