Lucky guy ! I also work with Google Cloud Platform and it’s really powerful, specially with Google Cloud Endpoints and Datastore. With my mobile app CookMinute (2000 users/day) I only pay 0,03$ per month with no latency at all. It’s really impressive ! I will soon update to Google Cloud Endpoints Framework v2, it seems to reduce latency a lot more.
By the way, did you organize some Meetups or maybe webinars to talk about GCP ? :) I may be interested !
