The thing is, even for smaller companies it's easy to get way better deals on bandwidth. I'm currently using a provider that runs openstack and I'm paying less than $0.009/GB, from the first byte(no commitment). I'd say that is very cheap compared to AWS pricing at $0.05/GB above 350 TB.

With colocation or renting dedicated servers and IP-transit you can get way lower prices. A dedicated 1 Gbps is about 300 USD/month with my provider, and the prices drops hard for dedicated 10, 40 and 100 Gbps uplinks.

Never used OVH myself, but they are providing 2 Gbps at £340/month for their highest quality bandwidth, and £64/month for bandwidth they think would be good for downloads.

I think using cloud providers for somewhat high bandwidth services are basically throwing money out the window. Until prices really drops(if they ever will) I'll continue thinking that clouds are for temporary workloads or prototyping with the ability to easily scale at a high cost.

At $10k/mo what you do is plop a rack in one of the well connected buildings in NYC, VA, SF, SJC, CHI and get either flat rate 10Gs or 1G commits over 10Gs. You should be paying between 0.55 and 0.75 per Mbit/sec on 95th percentile on 1G commit. You put into the same cabinet your edge nodes that actually would be pushing the traffic out and use AWS or GCP for your compute workloads.
