Joshua McKenty, co-founder and chief executive officer of Piston Cloud, what he calls The Enterprise OpenStack Company, was in on the ground floor of OpenStack's creation, working as he was on the Anso Labs team at NASA to build a compute cloud on top of open source platform Eucalyptus. The team eventually gave up on that and wrote Nova, which NASA uses today to power its Nebula Cloud environment, and Nova was ultimately contributed to the OpenStack project, which it formed with Rackspace. McKenty left NASA after Anso was acquired by Rackspace in 2010, and formed Piston Cloud in 2011 with co-founders Gretchen Curtis (also of NASA) and Christopher MacGown of Rackspace. Network World Editor in Chief John Dix recently caught up with McKenty for a deep dive on why OpenStack matters and where Piston Cloud fits in.
