The Tor Project has started a new system designed to help people start and run Tor bridges in the cloud using Amazon s EC2 platform. The Tor Cloud is meant as a way for people to easily set up new Tor bridges on Amazon EC2 and get them up and running quickly. Tor volunteers have set up and configured Tor images that will recive updates and security patches automatically. It should cost about $30 a month for others to set up cloud bridges. The project has set up five separate images for different regions around the world.
