Update with HA:
- Configure more than one front-end private IP address for a single
internal Standard Load Balancer resource.
- Configure multipleload-balancing rules, where each rule has a single unique front-end IP address selected.
- Select the HA ports option, and then set Floating IP to Enabled for all the load-balancing rules.
