Front End Servers, and in larger sites A/V Conferencing Servers, are the only components required for web conferencing.
Data Conferencing capabilities are provided entirely by Enterprise Edition Front End Servers, and Standard Edition Servers.
A/V Conferencing capabilities are provided by the A/V Conferencing Server, which is either collocated with your Front End Server pool (for sites with fewer than 10,000 users) or separated into its own A/V Conferencing Pool (for sites with more than 10,000 users).
A/V Conferencing Pools do not need to be load balanced.
