Well, if you are using VMs and the site cannot afford to go down, then the 50k visitor site does need a cloud load balancer. Individuals VMs can fail anytime. These cloud load balancers can be a part of your HA solution, but yeah.. one also needs to make all other parts of the infrastructure HA (or at least HA-friendly) for this to work as expected, which is not necessarily a simple feat. I hate being woken at night by emergency calls, so I would prefer to set everyone and everything up with HA solutions.
