Abstract
In embodiments of the present disclosure systems and methods implementing active-hot standby redundancy in server architectures are described. In an active-hot standby redundancy architecture, two matching service instances are installed in a network on different host computers. A standby service instance may maintain state information for every session maintained at an active service instance that it is poised to replace using a publish-subscribe communications network. When a failure occurs in the active instance, the standby instance may promote itself to active, and assume all aspects of the service identity and role of the Active instance it is replacing. Service to user entities continues without interruption, although transactions that are ongoing just as the failure occurs may be lost.
