Built on the machine provisioning power of Chef, Infochimps' Ironfan is a systems configuration tool that enables the entire Big Data stack, including tools for data ingestion, scraping, storage, computation, and monitoring. Spin up clusters when you need them, kill them when you don't, so you can spend your time, money, and engineering focus on finding insights, not getting your machines ready. In this talk/demo, we will actually spin up a Hadoop cluster in 20 minutes using Ironfan and tell you about some of the great projects folks in the Chef community have used Ironfan to enable.
