Why is clustering such viable tool?
With clustering every few seconds the balancers check the availablity of the web ports they are balancing. If a port fails it will remove the server node from the pool causing all traffic to be redirected to the other members in the pool. If all members in the pool go down all requests can be forwarded to another IP preventing total downtime and loss of traffic. This is what we call the Fallback host.
Being part of a web cluster the cluster appliances act as a Firewall, when you would goto your site www.site.com
you are going to whats referred to a VIP (Virtual IP) or Virtual server the only port this VIP is listening on is the ones that we tell it/allow. All machines behind the balancers are in their own Vlans in a private network. How do you access your server via ssh? easy we can still create a NAT to your machines so you can access them individualy or you can just access one of them and then connect to each one from that one box from the private network. *VPN access is comming shortly*
What if I use mysql and one of my machines goes down?
With the latest versions of mysql you can replicate your databases and keep them active just incase this was to happen. *Must use mysql 5.0 or newer*
