The thing here is that they're not using any of AWS's proper server offerings. There's no EC2 or Lightsail or even RDS. There is no thing or concrete group of things that you can point to and say, "There, those are my servers." It's based off API Gateway, S3 and Lambda, none of which is recognizable as a server in the traditional sense (though of course there are servers behind the scenes implementing the abstraction).
