alt Hacker NewsBack in the ancient era of the mainframes, this "multitenancy" concept would have been called "time sharing".
It looks like everything old is new again.

Fascinating how the wording has changed from sharing to tenancy. Maybe reading a bit more into it, but isn't it funny how the modern word evokes the landlord/tenant relationship?
(I'm reading into this further than it needs to go for fun, primarily)
It’s a common refrain on HN this thing is the same as something old. Dagnab those young folks!
I was kind of disappointed the first time I saw an IBM mainframe and it kinda just looked like a rack of servers. To be fair, it was taking up a little bit of a server room that had clearly been designed for a larger predecessor and now almost had enough free space for a proper game of ping pong.
Hyperscaler rack designs definitely blur this line further. In some ways I think Oxide is trying to reinvent the mainframe, in a world where the suppliers got too much leverage and started getting uppity.
Oh the memory. IBM3090 MVS with TSO...
If you stay around long enough the pendulum swings full circle.
