We are.  I'm just putting it in *our* cloud, not some random other

If you're keeping the storage, run some VM's alongside.  

Quite frankly, it's a little horrifying how quickly people have embraced
not owning their own resources.  On one hand, sure, it's great not to have
to worry about some aspects of it all, but on the other hand...

The web sites that we entrust our data to can, and do, vanish:

MySpace.  GeoCities.  Friendster.  Google Videos.  Which of those did
you predict would eventually fail?

The companies we pay to provide us with services screw up:

T-Mobile (Microsoft?) Sidekick.  Lala.  Megaupload.  RIM/Blackberry.

Arbitrary changes in terms of service:

Facebook.  Dropbox.  Google.

You know where I never have to worry about any of that?  On gear we own
and control.

"Cloud" is a crock of hooey buzzword.  There's no "cloud."  For the
average end user, it is the realization that we've farmed out tasks to 
unknowable servers across the Internet.  For the technical user, it's
setting up instances of servers in some large hosting company's big
data centers.  The "cloud" people refer to today is nothing more than
the continued evolution of virtualized hosting.

There's nothing magic about it.  You're trusting your data, your 
processes, or (most likely) both, to arbitrary other companies whose
responsibilities are to their shareholders and whose motives are
profits.  You have no control over the actual management, must trust
that they'll let you know if their security has been breached, and
you may never find out if someone's gone snooping.

It isn't somehow magic and new because someone calls it "cloud."
All this "cloud" stuff?  It runs on actual hardware, not up in the sky.
And as long as it runs on actual hardware, it'll run faster and better
and more responsively on equipment that's less-loaded, better-specced,
and much-closer.

Sun had it right all those years ago: "The network is the computer."
But it doesn't have to be Amazon's network, or Google's network.
We *are* the North American Network Operators' Group.  The people
here are more than just a little clued about this stuff.

I'm fine with running Netflix out of the cloud.  I can tolerate their
occasional outages and problems.  I'm fine with running other
unimportant stuff out of the cloud.  But it looks like it is going to 
be a long time before I have any real interest in running anything of
value out of someone else's "cloud."
