With the corporate mandates to achieve high application and service availability, a high availability solution with automatic failover capabilities ensuring seamless business continuity should be seriously considered. Conventional failover solutions can be limiting. Installation, configuration and maintenance of traditional high availability solutions often result in interruptions in service and prolonged downtime, often requiring considerable changes be made to the IT infrastructure. To overcome technical obstacles during automatic failover, especially with replicas located in different IP networks (in which case IP addresses cannot be transferred), an even more advanced solution is required. XOsoft?s WANSyncHA overcomes this limitation through intelligent manipulation of DNS lookup. Should the master server fail, WANSyncHA will route client applications to a replica server with an alternate DNS name, again providing users with continuous application availability through automatic failover.
