Chapter 4 Installing Cisco Unified MeetingPlace Web Conferencing Release 5.3 in a Load Balancing Configuration
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 16 web servers (including both internal and external clusters) to a single
Cisco Unified MeetingPlace Audio Server system. The two databases (one for the internal cluster, one
for the external cluster) must have identical GUIDS.
Cisco Unified MeetingPlace Web Conferencing supports five potential load balancing configurations, as
shown in
