HI John,
Thanks for the options and sharing your experience.
I'm only starting to realise what a can of worms this is ... and
it's certainly a topic where hearing the experience of others is
invaluable. So I hope Ged and Stas don't get too peeved if we indulge in
some [OT] load balancing banter. ;-)
I was worried about DNS caching and your IE experience does not
bode well for the round robin option. Did you set the TTL to less than 60
seconds?
Here are the suggested options so far:
* round robin dns
* RewriteMap
* djbdns/tinydns allows dynamic IP address changes for round-robin
load balancing and handling a failed server
* setting up a linux server as a load balancer -
http://www.linuxvirtualserver.org
* mod_backhand and wackamole
* Balance (http://balance.sf.net)
* Pound (http://www.apsis.ch/pound/index.html)
* custom application level redirects
I suppose there are two parts to the load balancing problem:
directing the hits (i.e., requests), and clustering the application.
'Directing the hits' sounds conceptually straight-forward - a bit
like watering the garden - so you would think there would be a clear 'best
way to do it' - so I'm sure I'm not alone in wanting to hear other's
experiences?
