Ubuntu Switches To OpenStack For Cloud

"Canonical has switched its cloud software stack to the open-source
OpenStack. The current version of its Ubuntu Server, version 11.04, uses the
Eucalyptus platform. Ubuntu Server 11.10 will include the OpenStack stack as
the core of the company's Ubuntu Enterprise Cloud (UEC) package. The server
release will also include a set of tools to help users move their cloud
deployments from Eucalyptus to OpenStack."
