About Installing Cisco Unified MeetingPlace Web Conferencing Release 5.3 in a Load Balancing Configuration
The following additional factors are taken into consideration when identifying which web server within
a cluster has the lightest load: each server's CPU usage percentage, memory usage percentage, number
of active conferences, and number of attendees. You can view the amount of web-conferencing load per
server from the Web Server administrative page. This information is only displayed on internal web
servers.
To configure load balancing, you should understand the following concepts:

Cisco Unified MeetingPlace Web Conferencing Load Balancing and Standard
Web Server Load Balancing
In standard web server load balancing, third-party software typically monitors incoming web server
requests and distributes the load by sending requests to different web servers. This can also be
accomplished by a DNS round-robin configuration.
With Cisco Unified MeetingPlace Web Conferencing load balancing, all users enter through one
designated web server. If they are all attempting to attend the same meeting, they are directed to the same
web server. Current server load is assessed in order to distribute web-conferencing load across the
various servers. HTTP (or HTTPS) requests are not distributed across web servers.

Cisco Unified MeetingPlace Web Conferencing Clusters

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