I have read two of very nice tutorials here, viz. 1) http://www.howtoforge.com/installin...tabase-cluster-on-debian-6.0-with-ispconfig-3 by Till 2) http://www.howtoforge.com/virtual-m...ns-servers-on-debian-squeeze-with-ispconfig-3 by Michel Both are very nice. Actually I am thinking of using a cluster (like 1 above) with split servers (like in 2) in openvz containers. However, though the tutorial 1 by Till categorically states that it deals with "fail over, load balancing and high availability", but is it only me that I see no such things except syncing with unison /var/mail and /var/www? It would be nice to if someone can exlpain how failover and loadbalancing is possible with two servers (either local or remote) which may look something like this (https://www.ovh.co.uk/dedicated_servers/ip_failover.xml) ? Thanks in advance.
