Cloud goes beyond rented VMs. Fully managed cloud services have thousands or millions of production customers on the same node. They have to be very careful about what they run as root.

I understand your point, but millions sounds an exaggeration- I have a hard time believing a single node can handle millions of concurrent users

[kqr]

I didn't mean to imply concurrent. A large fraction of the user base is very sporadic in its usage!

Thanks for clarifying :)
