"An organization may want to have some separation in its OpenStack deployment due to geography but still want to have an aggregation layer to see all resources," Bryce said. "Telcos and cable companies run a lot of small clouds, and they don't necessarily have a single massive environment."

For the last three years, OpenStack developers have been working on the issue of federated identity in the cloud. At the core of those efforts is the OpenStack Keystone identity project, which got a major boost in the Kilo release cycle to enable what OpenStack executives refer to as the OpenStack Powered Planet.

"Kilo was the first release where it was possible to have an OpenStack cloud serve as a federation authority," Bryce said. "In Liberty, that has been updated with new options in Keystone for different back-ends and improved federation protocols."

The Neutron networking project within OpenStack Liberty benefits from multiple innovations, including a new component called Courier, which is focused on container networking.

Mark Collier, chief operating officer of the OpenStack Foundation, said he is impressed with the high volume of activity in Neutron during the Liberty development cycle. "For the first time ever, Neutron is the most active project in terms of commits, while Nova had always been the most active before," Collier said.
