Load balancing strategies are used in a site configuration to distribute the load between multiple backend target servers. Load balancing settings are optional and only available if more than one target is listed for a site.
This functionality can replace a load balancer appliance between the PingAccess engine nodes and the target servers, allowing for a simpler network architecture.
The load balancing strategies currently available are Header-Based
and
Round Robin
.
The Header-Based
strategy requires the request to include a header that
defines the target to select from the Site configuration. This
strategy lets you fall back if the requested target is unavailable or if the header is
missing from the request.
The Round Robin
strategy has a sticky session option that permits a
browser session to be pinned to a persistent backend target. This strategy works in
conjunction with the availability profile to select a target based on its availability.
The load balancer will not select a target that is in a failed state.
