True geo-redundant hot-standby server architecture

Abstract

A server configuration provides a geo-redundant server that is ready as a hot-standby to the primary server in another location. This architecture can be easily implemented in a distributed contact center environment or any other server deployment where services provided by the primary server are mission-critical. One exemplary configuration provides a single active master server. This single active master server is responsible for making all service-based decisions, receiving and processing client requests, etc., as long as it is operational. A second server is provided at the same geographic site or location as the single active master and a high bandwidth active LAN connection is established between the two. The second server maintains synchronization with the single active master. The second server is also connected with a third server via a WAN. The second server provides the third server with the state information for synchronization with the single active master.
