Amazon EC2 Instances have metadata they can access. They get it by accessing a web server on a link-local address 169.254.169.254.
This PowerShell function will attempt to open http connection to the link-local address 169.254.169.254, and if successful will confirm that the host is running on Amazon Elastic Compute Cloud (Amazon EC2).
