Video explanation
An optical bench represents a request path. Switching a mirror redirects the signal from an old route to a load balancer and service nodes.
Path rules
A request’s URL path can affect routing and rewriting. Alternate beam paths represent a configuration change.
Choosing a target
A load balancer selects an available service target. Target groups and health affect selection.
Ports must match
The display calls out a registered service port. Real configuration must match the application’s listener; beams are a traffic metaphor.
