The most important thing is that it's easy for me as an non technical person, who knows nothing about databases or sql queries but just want my application up running fast without too much hassle of setting things right myself! I can't think any downsides at this point yet because we are still using infinitdb only once so far - which was quite simple actually since our app uses very little data compared other apps out there where you need more than 1GB RAM per instance!! We have several instances set aside already though if needed later downthe road when traffic increases again :).
