Cluster deployment

New feature in Flash Media Streaming Server and Flash Media Interactive Server; requires Flash

Player 6 or later.

You can deploy multiple servers behind a load balancer to distribute the application load evenly.

Flash Media Server clustering enables you to scale an application to accommodate more clients

reliably, and creates redundancy, which eliminates single points of failure. is approach is

cluster using server-side scripting. is option would typically be used for multiway communica-

tion applications that require connections be routed to a specic server. is option does require

development of rather sophisticated server-side ActionScript to manage connections.
