Yeah, but the headache is usually from database, cache and other shared resource servers.

Scaling HTTP has been very easy for most applications for the last 15 years or so.

I have to confess I really don't see the appeal of edge workers in general outside of specific applications where latency is of high concern. Such applications do exist, of course, but this kind of offering is treated so generally that I feel like I'm either immune to the marketing or I'm missing something important.
