what works financially is providing a fleet of simple similar independent machines.
think "your personal wordpress instance w/ own email and ftp server", centrally maintained, identical baseline but individual content.
to this day Linux KVM does not enable multi tenancy. with z/VM you can provide that, and you still have the shared /usr in physically shared ram in z/vm.
the physical CPUs are also virtualized and shared, each "full own wordpress server" only needs slivers of that cpu pool.
it was done and it qorkwd. and it was profitable for both the hosters and IBM.
- Spooky23 4y agoYes - that was very interesting one of the drivers for what I was working on was that the z/VM segmentation would allow for partitioning of workloads to avoid over-licensing and address some security needs. The tough part was if you didn’t have that perfect scaling opportunity, things fell down fast, and the marginal cost for more resources was way too much. IBM tried to oversell it.
