If you just want failover on the head apache: use two nodes with vrrp + keepalived (if you’re on linux) to monitor your service.
If you need load-balancing, then you should use two VRRP addresses with DNS round-robin. But you’ll stumble on client-server persistence problem if you don’t use tomcat clustering.

Hi,
Perhaps look at "haproxy" instead of apache. Run it on two or more machines with multiple IPs and have then distribute the load to your Tomcat worker nodes.
