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.
