In order to avoid loss of business, the JeraSoft Telecom Billing Platform for telecom retail providers offers a cluster billing solution which keeps data flowing even if one of the servers fails. The cluster consists of a Master server plus one or several redundant servers. These are backup servers that can take over instantly if the Master server fails. Under normal conditions, the master and the redundant server can be used for load balancing. If the Master server fails, the redundant server becomes New Master and takes over all duties.
