We use Capistrano[0] to automate releases in the same manner. It keeps multiple copies of the site in timestamped directories and has a 'current' symlink which it just points to the latest. If you ever need to roll back, just point the symlink to a different timestamp. Similarly, for our rails apps we use unicorn[1] to do no-downtime deploys. When we roll out new code, unicorn brings up new workers while the old workers are still running. The old workers are not sent any new requests, and once they finish their in-progress requests, they are killed.

We use it to deploy node.js apps as well. [1] http://unicorn.bogomips.org/ http://unicorn.bogomips.org/ A forking ruby http server
