As someone who tried building this for the unwashed masses, wait until you have something along the lines of Google Spanner. Developers see amazing gains from edge compute because ZOMG LATENCY, then actually flesh out their apps and start making uncached database calls back to AWS anyway.

EDIT: Yes they lack pricing transparency. Akamai is expensive. As I pointed out, in real world experience less than 5% of the developers I talked to actually could lower response times by moving closer to the client. It's something everyone thinks they need, but the devil is in the implementation details. Akamai hand holds you a lot for your money.
