Yes, so what? Its still something you need to cost out for an alternative.
> You could switch over to Google Cloud (AWS but from Google)
App Engine is part of Google Cloud (the AWS-equivalent umbrella of offerings). You probably mean "Google Compute Engine" instead of "Google Cloud" and "EC2" instead of "AWS".
> and still use Data Store
You could (Google Cloud Datastore seems to be very much the App Engine datastore outside of App Engine) but its then a separate cost you have to include in the comparison.
> or you could switch to any PaaS and use something like mongohq
You could, but its then a separate cost you have to include in the comparison.
