Excuse my naivety but isn't data store just a managed nosql database? You could switch over to Google Cloud (AWS but from Google) and still use Data Store or you could switch to any PaaS and use something like mongohq.

Yes, so what? Its still something you need to cost out for an alternative.

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.
