Re: Apache clustering w/ load balancing and failover

Why not use (keepalived?) with round robin dns then?. You get load
balancing, redundancy, and you don't need unnecessary additionnal
servers or kernel patches or whatever. Even with a lot of servers, it
should scale pretty well. Works too with servers in several locations on
different internet pipes, as long as there are at least two servers on
each pipe for redundancy.
Why not using 'roundrobin' ???
Install a couple of Web-Servers, give each Server an IP and
then setup for each Server a A-Record on your DNS-Server
pointing to the same hostname.
The problem with round robin is that when one server fails over it keeps sending them connections, I once saw a DNS server implemented in Perl which worked in a round robin fashion but making some kind of test to know if the server was up and running correctly, I remeber it was called something like "lb-named"
