Oh, a mainframe blog that quotes IBM numbers! Thanks Bill.
Don't take my word for it. There's a video and presentation that
describes the banking architecture I mentioned
https://www.confluent.io/kafka-summit-sf18/kafka-in-the-enterprise/.
That's the tip of the iceberg. I can spend all day posting more links to
other banks with the same event driven architectures. The mainframe is
critical to their core banking system but it's just a cog in the wheel.
I'm not anti-mainframe. I work for a mainframe ISV and I hope to retire
still working on the mainframe.
When you say all banks are you including neobanks and fintechs which
have exploded in recent years and disrupted the banking industry. I
moved my banking to a mobile app only neobank ages ago and have never
looked back. I still get a bank card and pay no transaction fees. I
enjoy the same
regulations and guarantees that I would get from a traditional retail bank.

9 Mainframe Statistics That May Surprise You - Precisely
How important is the mainframe today? One way of answering that question is to take a look at some mainframe statistics about how they are currently used.

I do almost everything important via app with a mainframe on the back end. Banking,
health records, retail shopping, insurance claims, investing. And with very high

I would suggest that almost all of those companies (banks, retail,
insurance etc) that run mainframes run a significant portion of their IT
systems on distributed systems. I recently met a software architect from
a bank who told me that the explosion of internet banking app usage has
pushed up the TCO of their mainframe to unacceptable levels. 70% of
those transactions were reads (folks checking their bank balances on
their phones). Their solution was use Apache Kafka to replicate the data
to Apache Cassandra and only hit the mainframe for writes.
Apache Kafka can be deployed on z/OS but it was crippled due to the
BPX1MMP (mmap) service being contained to 2GB. IBM have recently fixed
that which is another good example of mainframe modernization

That can certainly be part of it.
But it can also mean providing applications (typically web based) with access
to z/OS data, or interfaces. Whether that’s direct access to the data, or
access through a REST type interface. That way the mainframe can retain it’s
role as the system of record, and at the same time put a more modern face on
the applications.

I think it's related to the push for the z/OS Management Facility (z/OSMF) and
Zowe over traditional system administration and programming methods.

Does anyone out there know what is meant by the expression "Mainframe
Modernization' '? It seems to be catching on with the Bobs but when you
ask exactly how they propose to modernize their systems all you get is
silence. As in if you don"know we shouldn't even be talking about it.
Any ideas ? Or is it just more BS like 'cloud' or 'devops'?
