I'm torn between A and D. Persisting data to a database makes sense, but a truly stateless app might be the most Twelve-Factor-y approach. I guess it depends on the specific requirements.

Option A seems like the way to go. Persisting data to a local file isn't really cloud-friendly, and the Twelve-Factor methodology emphasizes using external services for things like data storage.
