so i am trying to achieve keycloak to be distributed between region without single point of failure

first i used postresql but one region will be write and other are read only and to make the other region write if the first region is down requires manuel work i don't see it practical

then i came across YugabyteDB i like it it's read/write distributed and is very good but i am afraid of race conditions so is it good to use it on production keep in mind that Keycloak project does NOT officially support YugabyteDB

1 for designate dns zones is the main purpose is that the private ip being routable through the public domain name without the floating ip association so i can ping + ssh my vm with that DNS name i got from designate?

2 for dns reverse if i have public ipv4 associated to one of my VMs and i have a domain name from namecheap how my dns reverse gonna tell every dns server out there that this domain lookup is this floating IP address

3 should the interface of dns_interface be identical to the neutron_external_interface?
