Server balancing

Hi all. Faced a non-trivial task. The meaning of the action is to implement fault tolerance in such a way that if one of the channels or servers fails, the domain will resolve to a live IP.
I want to clarify that such "chips" as the creation of AA records, according to the scheme: host has address хх.ххх.хх.хх has address хх.ххх.ххх.ххх
in a zone for the domain do not work. Due to the fact that with such a scheme, the resolve goes randomly on both IPs and in the event of a loss of communication with one of the servers, the packets will still go nowhere.
If someone knows a solution to such a problem with minimal labor and technological costs (do not offer AS + BGP), I will be grateful.

If someone doesn't understand, you need to do load balancing or duplication of two machines that will be interchangeable in case of a neighbor's failure (I heard that it can be implemented on a cluster with OBSD or pFSense, but I don't know how).
