Blah, blah, blah, blah.
I have a double-handful of clients with usable corporate computer systems spread across most of the continents on this dampish, muddy rock that we call "The Earth". Several are Fortune 500s.
Not a single one of my solutions contains the word "cloud".
"Distributed", yes. "Cluster", yes. "Grid", yes (one legacy system). "Centralized", yes. Even "Peer-peer" and "stand alone workstation with network availability on demand". Etc. But no "cloud", not anywhere.
IMO, "Cloud" is a reference to the old ISO OSI-model textbooks that used a "cloud" image to try to hide the actual networking layers below the so-called "presentation layer".
Enough non-technically-inclined managers "took a course" with outdated textbooks that this "cloud" nonsense entered the corporate vernacular when said managers moved into marketing (hint: If your school is teaching the OSI model, you're obsolete before you paid the course fee).
