Netflix works because they move content close to the users. This is done by either having the ISP establish a peering connection directly to Netflix hosted servers or by having the ISPs host "Open Connect Appliances" which cache the most requested content. These appliances are based on FreeBSD.

The AWS egress savings from this setup must be immense.

Yup, cloud bandwidth is insanely expensive considering to what you actually pay to get link to your datacenter.

And you pay either by 95th percentile (basically "peak usage") or by whole link, not per megabyte sent
