On premise can be a lot cheaper for bandwidth intensive app. We have a 10gbit/s dedicated fiber we use at like 80%, it cost us 1500$ per month (power+fiber). This kind of bandwidth is 10 to 100 times more expensive on the cloud depending on the service. Of course, no CDN, but as our customers are mostly local, we don't need global presence. Also, we serve this from a single epyc based server, using elixir/phoenix. It's at about 6gbit/s outbound traffic. I realize this is not uber redundant, but it works and keep the costs low.
