How is 'Inbound NAT rules' different from 'Load Balancing Rules' different from each other in Azure Load Balancer v2

问题

Can someone explain to me what actually happens in the back-end to the load balancer (v2) for the two scenarios:

1. Applying Inbound NAT rules.

2. Applying Load Balancing Rules.

回答1:

You would use NAT rule when you have 1 backend server or you know which backend server to get to and loadbalancing rule when you want to loadbalance to multiple backend servers.

回答2:

NAT rule must be explicitly attached to a VM (or network interface) to complete the path to the target; whereas Load Balancing rule need not be. In the latter case, a VM is selected (from the back-end address pool or VMs) to complete the path to the target.
