Returned a few days ago from NRF11. As expected, there were many companies advertising cloud computing, and yet, how disappointing when investigating the case a tiny bit further: it seems that about less than 10% of the companies advertising themselves as cloudy are actually leveraging the cloud.
1. Is there any specific reason why this app is in the cloud?
2. Is the underlying infrastructure larger than 100k machines?
3. Can you open an account and get started right from the web, no setup cost?
4. Is there a public pricing? Typically indexed on usage or user metrics.
5. Can two machines failing bring down the app along with them?
As a final note, it's rather hard to tell the difference between a well-designed SaaS powered by a regular hoster and the same but powered by a cloud. Although, back to point 1, unless there is a reason to need the cloud, it won't make much difference anyway.
