Redundancy DNS / Load balancer requirement

Hi,

We have 2 ignition gateways configured as redundant pair. And the configuration does work well. We have tested it using Force Failure on primary, Primary machine restart / shutdown. But for power failure / unplug it does not work. And we are using perspective.

Questions - to productionize:

  1. Will the DNS configuration be for the Primary gateway? While Ignition manages the failover?
  2. If DNS config is for primary only, how will it work in case of power failure or such situations? Do we need a load balancer? Or there is a recommended way IA has to suggest? OR Does the ignition gateway update the DNS records on failover?

The IP addresses of both the master and the backup gateway have to be resolvable using DNS. Perspective sessions use both redundant gateway addresses, so that they can redirect to the backup gateway if the master gateway can no longer be reached. And for something like power failure of the master gateway, Perspective sessions should definitely be redirected to the backup gateway.
