Cisco released the first version of its OpenStack Cisco Edition late Friday. Cisco has been an active participant in the open stack ecosystem since at least January of 2011.
The Cisco Edition of OpenStack does not include its own core operating system, which is required to be installed first by users. Currently, Cisco's OpenStack release has been validated to run on Ubuntu 12.04. Moving forward, Cisco is looking at supporting other Linux distributions, including those based on Red Hat Enterprise Linux (RHEL).
