I'm just starting with Rails and I've found Heroku the easiest Rails hosting provider. They don't give you a shared server machine, you upload your application directly, and there's even a free usage tier if your app is low-traffic.<p>Using git, you just push the app to Heroku with your credentials and you're set.<p>Also, you can upgrade or downgrade the maximum performance as needed by the spikes of traffic so you never pay for more that you use.
