Having recently gone through the exercise of trying to understand what these 
different terms actually meant, I discovered that the underlying problem is that 
you are both right, as are a variety of other people who have other views...

As already noted, the term 'cloud' is now used in many different ways, including 
as a synonym for 'network' and for 'Internet', even amongst technical folk. 
(Really.)

There are some people who have very specific and nuanced technical definitions, 
including distinguishing cloud from grid.  But no set of definitions seems to 
have a broad base of support.

For defining 'cloud', one group I'm participating in decided it was happy with 
the NIST language:
