Load balancing involves promising a 100% uptime for a server application.
Load balancing only eliminates downtime due to server/application
being a single point of failure.
Even with full redundancy it's still not possible to provide 100%
uptime for any application. You may be sharing the same ethernet
switch, ISP connection, etc. In the very least the clustering software
is a single point of failure. If VRRP breaks then you'll end up with
a multi-master scenario where your cluster stop working.
