Radoslaw Skorupka got some good answers to his questions, but I can fill
in some gaps:
2. While z/TPF can certainly run as a z/VM guest, that's at least not
common for production instances.
3.1. There's a base z/TPF license plus some popular options such as the

Well,
I thought there are important differences:
- hotels usually have more "seats".
- hotel have no time schedule for departures and arrivals. You cannot
book a seat 5 minutes after departure, while in hotel it is possible all
the time. IMHO this is the most important difference.
- of course
You'll find a bit more discussion about it on the VM listserv. While z/OS is a
requirement for the care and feeding of z/TPF, we use VM extensively as a
development and test platform. And yes, a hotel is an airplane without wings.
We used TPF for rates and inventory at Holiday Inn/BHR/IHG
e to today's
budget airlines who are using other platforms for reservations.

I think the limit was 32 z processors in an LPAR. They might have
raised it by now. z15 can have 190 in high capacity order.

zTPF is great for any high volume transaction where there are few
transaction types but many per second (IBM claims million tps) and at low
cost. The tradeoff is constrained application function,
Been around for decades as the airline system but usable by any industry
