i can easily see this happening. I built a serverless app github.com/cmdcolin/aws_serverless_photo_gallery and that is pretty bare bones functionality and it's already a pretty crazy system, hard to test, etc.
I know this is more about Rails than serverless but if you want an easy deployment experience my personal recommendation is Dokku, cheap as chips and super easy to get started even if you know very little about servers. With regards to rails it's a breeze to get that running on a server.
