Web Conferencing Clusters

With Cisco Unified MeetingPlace Web Conferencing, you can configure up to three web servers into a cluster, and you can configure clusters as either internal or external.

Internal cluster—Places all web servers behind the firewall inside the private corporate network. Typically, all web servers in an internal cluster display the full-access Cisco Unified MeetingPlace Web Conferencing interface

External cluster—Places all web servers between the private corporate network and the Internet, such as in a DMZ. For increased security, all web servers in an external cluster typically display the attend-only Cisco Unified MeetingPlace Web Conferencing interface.

You can attach a maximum of three web servers (including both internal and external servers) to a single Cisco Unified MeetingPlace Audio Server system. The two databases (one for the internal server or cluster, one for the external server or cluster) must have identical GUIDS.

Web Conferencing supports five potential load balancing configurations, as shown in Figure 4-1, Figure 4-2, and Figure 4-3.
