Some bare metal providers have allocation based on server provisioning rather than specific egress limits. But CloudFront is cheaper with commit pricing because CF commit pricing is very very cheap and you have to factor in the cost of said reverse proxy nodes and only so much can be delivered per node. As you factor in management of the nodes it becomes even more favorable to the hyper scaler like CloudFront.

I have seen large scale deals where CloudFront comes in cheaper than what the smaller CDNs built on bare mantel can reasonably offer even with sizable commits.
