SDN/OpenFlow has Cisco jumping

You can gauge the promise of an emerging technology by the reaction of the biggest legacy player potentially threatened by the new arrival.

Don't flush privacy in the name of security

IT pro rethinks infrastructure from the ground up, ends up in clouds

Mark Adams, vice president of IT at HireRight, is living the dream -- the chance to completely rethink the infrastructure for a $300 million software-as-a-service employment screening service company. While the nucleus of the 1,600 employee company has been around for 30+ years, a three year acquisition spree resulted in data center sprawl, leaving the company with 10 facilities, including company owned and collocation and disaster-recovery sites, some of them overseas. Now HireRight is three quarters of the way through a consolidation effort with a heavy emphasis on cloud. Adams gave an update on the company's modernization progress to Network World Editor in Chief John Dix.

Piston Cloud has made the tough private cloud decisions for you

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.
