It can mean a lot of things

When people talk about Gmail as a cloud service, then the open source
alternative may just be an instance of Squirrelmail running on a hosted
server.  Some people may use the word "cloud" in a very general sense
and describe their mail server as an private cloud service powered by
free software.

Then there are dedicated IaaS solutions (like XCP and OpenStack).

One of the aims of the users of these services is to treat them as
commodities: so somebody could start running their business on an
OpenStack cloud operated by an ISP but they could migrate all their
application images into OpenStack on private hardware in future.  It is
not so much about federation as it about avoiding vendor lock in (like
with document formats)
