Hi,
I got a server with 16GB memory, want to install 2 BIND on CentOS, one cache only and another authoritative. Is it better to install 2 OS virtually and run BIND in them or run 2 instances of BIND on the same OS? I mean what is the best practice to take advantage of the hardware resources without risking having single DNS with cache and authoritative?

If you really care about separating the cache and the authoritative part you should also use separation at OS level. There are light-weight virtualisation solutions like OpenVZ which does not add noticeable performance costs. On the other hand you might also go ahead with one instance and views.

Regards

Andreas
