This raises a good point. Would anyone be willing to give some examples of use cases where egress to cloudfront or ec2 isn't viable? Most useful computations I can think of involve consuming large amounts of data and simplifying it to some easily digestible result. Media streaming is the first and only example that comes to mind, but I'm sure there must be others.

Wouldn't a lot of that stuff be better done on GPU instances, even at a higher per hour cost?

EC2 also has GPU instances, right? The p2/p3/g3/g4 series.
