It's been said, those who do not understand Unix are condemned to
re-invent it ... poorly.
We could have a lively discussion about that on this list, but likely we
all agree that those who don't understand mainframes are condemned to
re-invent them (poorly).
I really don't know anything good or bad about LzLabs, but the article
starts with that "mainframes are a pain, but we need them (or need what
they do), and those with skillz are turning grey", and then suggests
that companies can "define" some ethereal thing rather than interest and
train people to roll-up their sleeves.
Yeah ... sounds like cloudy PSI.
What I don't get is how alternate "hardware" addresses the tech debt
problem.
Those who do not understand [technology xyz], especially those who
refuse to bother learning it, are condemned to re-invent it really
really poorly.

seems enthralled with LzLabs, but the article doesn't really shed any light
that I can see.
Consider statements like:
*Yet, while considered robust and reliable for certain uses, mainframes are
costly to maintain and difficult to support, particularly due to the
imminent retirement of those with knowledge of a system’s inner workings.*
OK, we can debate this (and have), but then:
*Cresswell described the migration process: “When an application is moved
from the mainframe into our environment we don't recompile it or anything
like that. We literally take the binary code that comes off the mainframe
environment,” Cresswell explained.*
How does this help with the maintenance issue? Do you keep a real z for a
dev platform?
Next graf says:
*“At the time we put it into the container we replace all the APIs with
contemporary ones that reference our software defined mainframe container.”*
Um, right. So that
L R3,540 Get TCB address
statement is going to get replaced? Or just replicated/emulated? Or they're
going to emulate all of the data structures in z/OS?
Or is this all a shell game, and it's really just Herc in the cloud?
I'm not opposed to someone doing something to shake things up. But the lack
of detail from Lz is starting to smell like PSI redux.
