I was really hoping for a bit more meat in this article. Perhaps some discussion on their caching strategy, or how they're building their JSON (i.e. traditional model-based #to_json approach, or something along the lines of Rabl).

Thanks for the feedback, i'll try and cover all that in a future post.

Agreed, not much to look at here. I would also be interested in hearing why they decided to roll their own platform instead of using a PaaS, given the small team size.

Why would you actually go with Rails compared to a smaller framework? If all they are serving is JSON wouldn't something like Sinatra be better? Less fancy stuff they probably don't use anyway?

Linkbait; there's nothing here about either scaling or an iPhone app.

I see the EC2's are in different regions but not the RDS, can you choose which region your put your RDS in or is that not a factor?

According to the picture; does it mean that you have 4 instances (Rails) serving all traffic? I know that you can scale it horizontally. But, at the moment, is 4 the real number?

To clarify they said "availability zones", not "regions", which is a huge difference in terms of latency. And yes, you can tell RDS which availability zone to use.
