I think I've also pointe out that public cloud is expensive. Further,
any cloud environment is too big for just a single user working alone...

See above on the cost issue.
Cloud environments are not single systems like mainframes. And the types
of guys you're talking about that don't fit the average user are 1)
fully capable of having their needs met (in fact I pointed that out in
my example) and 2) believe they contribute much more than they really do
in reality. The only business where I have seen bigger egos and
prima-donnas is the music industry.
...And I think if we're in a situation where EMP is being used, we
probably have much bigger issues going on than system availability in a
commercial or private data center. ...Or are you the one who will be
stepping over people lying on the floor bleeding, racing to get to the
backup tapes?... :)
