I typically deploy on slicehost, so I setup a 256meg slice [$20/mo] and put nginx [http://wiki.nginx.org/HttpUpstreamModule http://wiki.nginx.org/HttpUpstreamModule] on it to split the traffic. This configuration can handle enough traffic that if traffic became an issue, I would be making enough money to move the application to a dedicated environment.
