Our app is mostly hit during business hours. So we wrote a pinger to "wake up" the back end lambdas when a user visits the website (not log in, just hit the site anywhere) *and* it's been more than 5 minutes since the last ping. It's not perfect but it helps a lot with the cold start times.

Our problem wasn't with zero traffic cold starts (nothing is calling the Lambda), but rather with scaling up cold starts (oh damn, traffic! We need more lambdas!).
