What’s this “cloud” stuff I keep hearing about and how do I use it?

In this talk, learn about the various cloud based services which are out there and how to get up to speed quickly on each. Should you go with Amazon EC2 or Rackspace Cloud or Linode? Maybe Heroku or Google App Engine or Joyent’s no.de service? Each has their specific use cases, so learn why you would pick one vs the other. While it’s interesting to learn the overview, don’t stop there! Dig right in and follow along getting up to speed quickly on several of the most popular options. This is a hands on talk, so be ready to follow along as we present the getting started section!
