  If your servers are efficient enough (and this is not hard to do these days), it's easy to get bandwidth-limited on a per server basis, i.e. your server could handle more traffic, but you've maxed out the bandwidth available to that particular server. If you can load balance at the client, then you can "talk" to any server at the edge and don't need a router or proxy, so the net result is that you are only paying for whatever bandwidth comes with your OVH (or whatever) boxes. Effectively, you're buying bandwidth and the computer/storage/power/rackspace/etc. that comes with that bandwidth is free. And yeah, it's ridiculously cheaper than AWS or Google's Cloud Platform to do things this way.
