Clouds ...
.. are those fluffy white (or sometimes grey, even black) things in the sky aren't they?
They provide rain, hail and snow - all of which can be beneficial or detrimental to humans (and animals). They are not solid, they are ephemeral (unless you live in the UK - in which case, granted, they are fairly permanent).
So by calling this digital thing clouds what we are really saying is:
1) Like natural clouds there's a good chance it won't be there a lot of the time.
2) You could get a hell of a lot of damage caused by the cloud.
3) The only time the sun really shines and you can get work done is when the cloud is NOT there ("make hay while the sun shines").
4) There's some chance you'll be totalled in a lightning strike from the cloud.
5) You'll be depressed by the cloud (cloud is associated with depression - ("I feel like I've got this cloud hanging over me").
6) You'll be involved in a pile up (low cloud - otherwise know as fog) and lose all your data.
No points to whoever thought this name up!
I don't see what was wrong with calling it "Big Brothers Eye" or something honest like that.
