I have yet to read a definition of 'edge' that makes sense to me, sysadmin/infrastructure/coder of ~30 years in the industry.

Anyone?

In this case, instead of putting everything in a couple giant DCs (eg us-east-1, put PoPs (point of presence) as close to end customers as possible. that way, round trip times between the pop and the customer is as small as possible, making their experience better. Edge then simply refers to those PoPs collective conceptually; edge compute is then just running code on those PoPs.

Ok, got it. So this implies installing equipment in a number of PoPs presumably based on some study of where your core customers are? And I guess this isn't for all application logic, just cache stuff, quick and easy interaction gains, and none the less still passing heavy lifting back to the DC?

Presumably.

As far as app logic, it depends on how much you can get the workers to do in their allotted time (which is short, iirc) so yeah, imo you still need heavier resources in a DC.

Thanks!
