I'm curious, would this adds considerable amount of latency to the DB queries? I'm guessing connecting to RDS from an EC2 instance would have less latency compared to connecting to RDS from a Heroku or DigitalOcean instance, but how much is the difference and is it significant enough?

Heroku's hosted on Amazon servers, so you still can have your app and db in the same data center
