Utilizing a mixture of open source tools (such as Chef, Nanite, CouchDB, and RabbitMQ) and battle-tested techniques, Adam and Ezra will show you how to build an infrastructure that’s easy to manage, integrates with your application, and is self-documenting.

We didn't do a blog post for Chef 0.7.2, as it was released in the midst of VelocityConf. And thanks to our observant community, we're releasing Chef 0.7.4 earlier than originally planned to fix a few bugs that crept in. Speaking of community, it's time to honor our MVP.
