Greg DeKoenigsberg is VP, Community for Eucalyptus Systems.  Cloud + open source = unlimited awesome.  He has been with Eucalyptus since September 2011.

He was, once upon a time, Senior Community Architect for Red Hat, where he worked for nine years.  He is a former chair of the Fedora Project, an open source software development community with over 10,000 volunteer contributors.  He serves on the advisory boards of several open source advocacy organizations, writes about open source issues, and speaks at open source events worldwide.

He also shoots his mouth off sometimes.  He should probably be more temperate, but eh, what can you do?
