Deploying modern web apps (apt vs pip/rvm)

[Mark Mims]

We've been working hard to improve this very problem on Ubuntu Server.
Take a look at juju (juju.ubuntu.com) which lets you manage your
application stacks consistently.  In particular, take a look at
jujucharms.com/charms/precise/rails,
jujucharms.com/charms/precise/node-app, and
jujucharms.com/charms/precise/python-django.
