How to detect Azure/Amazon VM

Question

Is there any way to detect, in general, if your code is executing on an Azure or Amazon virtual machine. I am not referring to some sort of web or worker role in particular,

Answer 1

You could look at the machine's ip address, and determine if it is in a particular cloud's ip address block.

For Azure, the published list of ip address ranges for each subregion is an xml file at:

Amazon will post a blog entry when they add new ranges. They are currently:
