We have quite a bit of environment on “cloud”. We are using our own domain names. For this purpouse we stood up a BIND9 DNS instance on CentOS 7. And, this being the cloud, we enabled key based dynamic DNS
for instances to register themselves when they are spun-up. We have a single master and multiple slaves. all is well, untill mater goes down and we need to spin-up additional instances. Single master has become somewhat of a bottleneck
I have looked around, not able to find any solution, for a stable Multi-master DNS setup (outside of Windows AD).
Does any one have any specific pointers?
-Thanks in advance
