When requests come to your load balancer, it distributes them across your pools and origins according to three factors:
- : Traffic decisions start with which pools and origins are available and should receive traffic.
- : Policies set on your that route traffic to attached and available pools.
- : These are policies set on each that route traffic to available origin servers within the pool.
When a pool or origin becomes unhealthy, your load balancer and pools redistribute traffic according to these same policies.
