"Today, the Ubuntu project announced that future versions of the
Ubuntu Cloud will use OpenStack as a foundation technology.
OpenStack, the rapidly growing, open-source, cloud platform effort
founded by Rackspace and NASA in 2010, has secured more than 53
commercial companies including Dell, Internap, Intel and Cisco to
join the IaaS cloud computing initiative since launching. Ubuntu
officially joined the OpenStack initiative in February of this
year, but it is not currently providing commercial services for it
as part of the releases of its most recent Linux-based operating
system, Ubuntu Server and Ubuntu Enterprise Cloud. However, with
this announcement, OpenStack will become a core part of future
releases. While no longer the foundation technology for the Ubuntu
Cloud, Eucalyptus will remain within Ubuntu and will be available
for users who prefer this technology."
