I have read two of very nice tutorials here, viz.
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.
