Re: [PLUG] Load-balanced HA cluster

Load-balanced or HA? Which is it? Are you doing Active-Active? 

If it's just a web app and you have no need for e.g. disk fencing, a simple third load balancer on the front end (HA Proxy, for instance) could work wonders. Or you could use Varnish or Apache Traffic Server to spread load across the web servers.

Just make sure you enable session stickiness, regardless of which tool you end up using.

I'm soon going to need to set up my web app (served up by apache/centos5.5) with redundancy,  load-balanced with failover.
Last time I did this was 2007 or so, using RHEL and heartbeat with a virtual IP address pair.
What's one or more of the best ways of doing this today? Any nice shiny methods in the past few years?
