What is Load Balancing?
Load Balancing is the distribution of workloads across computers and networks. In streaming, load balancing is used to distribute playback client connections among edge servers to scale live and on-demand streaming.
The Wowza Dynamic Load Balancing AddOn provides a method for dynamically distributing connection load among multiple Wowza edge servers. Load balancing is used in tandem with the Media Cache technology and a live stream repeater (origin/edge) configuration, which are used to scale live and on-demand streaming.
