As I understand it the cloud is just a file server that you may also be able to run processes on... something we called "the mainframe back in the late '70s or early '80s. Yeah you could save files on it, you could run batch processes on it... then we came up with the personal computer... apple or ibm... suddenly you were saving files locally on your 10meg HD, and running your processes locally.
Then HD capacity increased at a nice clip... but you had to do your own backups... and everyone feared the HD crash.
Now the cloud appears... which near as I can tell is just a return back to mainframe servers hidden in some closet somewhere... just like the old days.
So is the cloud just a return to mainframes?
