Subject: Re: [ANN] Introducing SwitchTower: Distributed deployment for Rails

David Heinemeier Hansson [mailto:david.heinemeier@gmail.com] :

#SwitchTower is a utility for executing commands in parallel on
#multiple machines. It lets you (among many other things) deploy
#distributed applications with a single command.
#
#When your application is young you may be deploying it to a single
#machine, which runs the web server, app server, and database all
#together. In this situation, deploying manually is not unbearably
#painful. But as your application grows you may find yourself needing
#to deploy your application to two web servers, four app servers, and
#two database servers, atomically. This is where SwitchTower steps in
#as a pain-killer.

i'm a nuby on rails/ruby/web and i've played w your magical rails framework. It is really amazing. My q is: Assumming i just have the sample rails running on one host, and i want it to raise to 3 tiers on 3 hosts (web, app, db), would switchtower take care of the division by just pointing what host to put the web to, the app to, and the db to? The reason i am asking is that i do _not_ know anything about the application layer part (since i just see the rails app as just one coherent stand alone application) and i want to see what is the application layer side, the web side, and the db side.

sorry for the dumb newbie question.

thanks for rails and kind regards -botp
