So, say you're saving $2500 a year? That seems pretty cheap for an option to scale up without fundamentally changing your operational architecture.

The bigger question mark than the money, I think, is whether this scale up approach actually works, or whether you end up fundamentally changing everything anyway. In my experience it's a mixed bag. There are some advantages, but it also isn't a panacea, and certainly isn't as easy as turning that dynos knob on heroku was. But at the end of the day, I land on it being worth it for a business (though not for a hobby). But it isn't a no-brainer.
