I wouldn't exactly say the title is misleading, because it still is an address failover between cloud networks. But your points about the public addresses is of course correct.

The key application here is for those who wish to establish hybrid clouds, want to "cloud burst" their enterprise capabilities, or - as the opening sentence of the article explains - about "[organizations] moving part of [their] network and server infrastructure into the cloud".

And especially for those internal enterprise applications, running an HTTP proxy is not always possible.

You're right. I read the article through a public-internet lens -- a difficult bias for me to shake. :) I can definitely see the value for enterprises. I do very much like that the application servers are using the same tools they would if they were neighbors in a rack.
