So I typically host my projects on either Amazon EC2 or through iWeb.com's dedicated service. When I went to launch my new portfolio site, I realized that I Heroku would be a good fit, and their free service would be perfect for me.

Getting a project that is already using git up and in production is as simple as:

gem install heroku
heroku create app_name --stack bamboo-mri-1.9.1
git push heroku master

Specifying the stack makes sure that it will work with rails 3. Plus why not take the extra performance of ruby 1.9

Deploying with git will take a little getting used to, so I may end up creating a capfile that just pushs.
