I wish people would use a more accurate term than "cloud". According to the current wishy washy term "cloud", I was doing "cloud" 40 years ago on VM. Each user has their own userid to run VS1, it had shared read only mvs system volumes, a r/w mini disk with spool and paging, and a r/w "user disk" containing user.parmlib, user.proclib, and the user's data sets. I always had a spare "user disk" set up. if someone wanted a VS1/OS2 system, I gave this minidsk to them, and created another user disk.
When "cloud appeared on mid range" we had someone senior present on it. They were not pleased when we said we had been doing this virtualisation for about 20+ years. It all depends on what you mean by the term "cloud". (It reminds me of a discussion with a mid range developer who said a product had to support a large number of userids. After half an hour of going round in circles I found he thought 1000, was a large number of userid. I said on z/OS 100,000 userid was a larg-ish number. - it all depends on what the term means.)
