There is a cost, because you may have to change your infrastructure to
support URLs directly addressing individual servers within a cluster,
and you have to add a different kind of load-balancing to handle when
individual servers are taken down in the cluster so another server can
take over those URLs for the clients still using them.

But I agree that you might be able to use existing URL-based front-end
load-balancing kit, and that might reduce the cost of implementation
substantially.
