With all due respect, Brian, it's really not. With cloud
computing you're typically dealing with multitenanting issues
and a bunch of other layer 8-9 stuff that tends (of necessity)
to be reflected down the stack, and I think I can see an
argument for cloud computing belonging in the RAI space,
or at least having substantial overlap.
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:
