WOW, I really had no idea it would be this significant. No wonder IBM sales people don't
sell Linux to replace z/OS. So conservatively, 90% reduction in costs for any application
that moves? So about 5 mips (a p390 worth) would pay for any "Velocity costs"? Amazing.

z/OS $7,300 $1,980
z/Linux $447 $61
Of course, this does not include the cost of any Velocity Software
products on z/VM :)

Gee, next it will be the high cost of z/OS that you will be looking at.
How much do you
save if you move an application from z/OS to z/Linux?

Couldn't be 'QUICK' enough for us. We managed to eliminate it from VM
by
the middle of last year. We went back to using basic mode CTC
connections
to z/OS until they got themselves up to 1.7 with the ability to use
TCPNJE.
The interesting thing was that it was the huge cost of VTAM that was
the
main motivation for us. Given that the product was functionally
stabilised
and needed virtually zero support for a number of years we were
struggling
to see why.
Once we looked at VTAM, and eliminated it, this led us to look at a
number
of other relatively high cost products that we have ways to eliminate,
replace or reduce. I am not saying that we would not have looked at
these
anyway but the high cost of VTAM was the catalyst to start looking.
