cloud.torproject.org describes an image that can be used in Amazon E2C service. It mentions that this image is already configured with package updates and port forwarding.
The images have been configured with automatic package updates and port forwarding, so you do not have to worry about Tor not working or the server not getting security updates. Get started with Tor Cloud
But I am not able to find this image nor download it from anywhere.
Where can this image be downloaded from?
Currently, I am using Ubuntu 14.01 LTS with Tor installed from Tor repositories and have the relay up and running. I would like to know better options.
