Yes, I use DNS Made Easy for this use: 1) Create an A Record for each Memcached server with the SAME name memcached.domain.com 2) Create an A Record for each Memcached server with a UNIQUE name memcache.00.domain.com
Then do: $ dig +short memcache.domain.com # This returns --> 10.0.0.1 10.0.0.2 10.0.0.3 ... This gets the list of Memcache servers by IP, You can also use the "unique" names for DNS Access. Or just use the Ip values as you like. As I add more server to "Scale-Up" the DIG command just returns more addresses. So the idea scales. The A records as DNSMadeEasy can be updated with DDNS API calls. I like the performance, but have had issues with DNS performance. I just wanted feedback as to other system level users do this "scale- up" operation in production. Pushing new code works for some users. But lacks a dynamic update for OPs needs. Edward M.
