Re: Apache/Cluster issue -- Single public IP address

[James Hogarth <james.hogarth@xxxxxxxxx>]

I was wondering this myself (we use F5) but if he doesn't have the budget for a  redundant pair of F5's )they are pricey...) then he may be trying to get resilience this way....

That said a single front end apache server with mod_proxy and load balanced across N nodes (depending on front end firewall too) might be simpler overall....

You sure you have the right solution? Using RHCS for web serving
seems really complicated, I would use a load balancer instead. Myself
I have most experience with F5 gear but there is LVS on linux(never
used it). With load balancers you can often offload things like
SSL, compression, etc. It makes life much easier for scaling, since
you can have multiple systems serving content for the same public
IP, and add/remove more at will, really trivial to manage.

Depends on the size of your cluster..
