I have a zone in Route 53; let's call it
example.com. I have three A records in that zone:
server1.example.com --> elastic_ip_1 server2.example.com --> elastic_ip_2 server3.example.com --> elastic_ip_3
I want to add a new record to Route 53 with the name
server.example.com so that a DNS lookup of
server.example.com will return one of the three Elastic IP's listed above, chosen randomly and with equal probability.
How do I add this new record?
(Note: these services are UDP-based, so we cannot use the Elastic Load Balancer.)
UPDATE: I would prefer not to use an A record with multiple IP addresses as this would have to be updated each time one of the underlying A records changes.
