Ever wonder if a website is running on the cloud? Is it cloudy was created to answer that exact question. You simply type in the url and we do the rest.

How does the magic happen? It's simple. Using DNS and WHOIS we can determine if a website runs on the cloud and which cloud it runs on. The clouds that are currently supported are: Amazon EC2, GoGrid, Joyent, Linode, Rackspace, Slicehost, SoftLayer, Windows Azure.
