"On the cloud front, the new OS comes with the Aeolus
Infrastructure-as-a-Service (IaaS) system, which allows cross platform
control of cloud environments – controlled via a web portal, as well as
the OpenStack IaaS platform. For the more security-conscious user, the
Fedora build also has HekaFS, a cloud-ready version of GlusterFS that
supports encryption and strong authentication protocols."
