I don't know of any multi-location IaaS vendor that doesn't provide a consistent API across their availability areas. This can't be described as a special characteristic of AWS but the default position of IaaS vendors. When would an IaaS vendor actually have different APIs by location? I can't find any use case or example.

AWS may have more locations due to its size but on the flip side it is one of the most proprietary platforms. You are into a sort of Apple versus Android debate here. If you use Apple a lot its great but its compatibility with non-Apple isn't good. The question is does AWS make it easy to migrate OFF AWS or to be compatible with other clouds and standards? The answer is clearly no. That's fine but customers need to clearly understand that approach and its implications for their own cloud infrastructure strategies especially when outages occur.

Kind regards,

+1. AWS is the single largest multi-region IaaS vendor that provides a
consistent API (across regions). If the apps were designed for failing
over to an alternate region, all the bare metal capabilities do
already exist to solve this problem (ELB, anycast DNS). Netflix, for
example, runs in 3 different regions (see @adrianco's tweets).

I wouldn't say the same to PaaS vendors (built on top of AWS) that put
all their apps in a single location. That was fail.
