I was working on an app which serves roughly 400*10^6 API requests/day.

One cool property of our app is that it's rarely updated and mostly read.

And the goal is to achieve the lowest possible latency at the edge.

It scales beautiful, I am not sure which other architecture can help us keep this afloat with only 4 developers working on it.

So, we have a DynamoDB table which is replicated to multiple regions using DynamoDB streams and Lambda.

For us, Lambda means achieving a lot without many developers and system administrators but I understand that not all problems yield gracefully to this pattern.

It seems using Cloudflare Workers to trigger our Lambda function instead of API gateway could prove to be cheaper.
