Nearly every bank in the world runs a mainframe. That’s a fact.
I'm calling BS. None of the challenger banks (Startling, Yolt, Monzo,
Moneze, N26 etc) run mainframes. They have millions of customers and are
gaining millions by the week at the expense of traditional banks.
You live in a fantasy world!

Bill,
Youre barking up the wrong tree man. Most banks dont run their own DDA
(demand deposit accounting) applications these days.
Most of them use a service provider ... like Jack Henry...

Not in my wallet. How did they like the AWS outage? I looked at their
Facebook page. Looks like a bunch of unhappy customers. 1 bank out of the
top 100. Impressive.

Banks will never do what’s economical at the expense of risk.
Mitigating risk is what banks do. The mainframe continues to get MORE
ECONOMICAL, safer, more uptime, faster. The clouds have been around
for a decade or more and how many banks have transitioned to the
public cloud from a mainframe?
Capital One?

And that's where we disagree. Banks will do whatever is most
economical
that still meets their needs. If x86-cloud doesn't meet those
requirements today, they stay on the mainframe. Tomorrow... only the
shadow knows.
People say OS/2 was far better in design, operation, and security than
Windows, but it's gone now. Sometimes the "best" system is simply
what
everybody else is using. Got to go now because I just put in a
betamax.

Do you put your DR placement right across the street from your data
center? Consolidation is bad. Exposure for everyone in the same place
is a disaster waiting to happen. Like last week. It’s why truly
important functions like banks don’t do clouds.

Of course... military has the money (the $500 hammer?) to have
redundancy on their redundancy. Business installations normally can't
justify those costs.
However, I think if we looked close we both might be surprised at all
the various baskets AWS has behind the scenes. But like any basket
collection, there are always single points of failure.

You’ve just described what the mainframe does for an organization.
But, I don’t want every organization to have its eggs in one basket
any more than I want every nuclear weapon in one silo.

backups, DR, procedures, dual this, dual that, etc.

This paragraph concerns me.
One of the founding principles of the early Internet design was
decentralization – by design, a single fault would not be able to
take out everything. In a way, today’s reliance on large cloud
providers removes the benefits of decentralization; we rely on the
scalability, cost effectiveness, and flexibility of today’s SaaS and
Cloud offerings yet we are potentially putting all of our eggs into
one basket. This same statement applies to CDNs, as seen with the
recent Akamai outage from this past summer.
This was one of the drawbacks we experienced when our GM subsidiary
(and all GM subsidiaries eventually) combined into EDS data centers.
Charlotte was where ours was located. If the mainframe went down in
Charlotte, multiple GM subsidiaries were screwed. Costing GM tens of
millions in highly paid union labor twiddling their thumbs.
If an ETSY business owner selling crocheted scarves has a 4 hour
outage, it’s probably not that bad. If an auto plant, bank or
brokerage, health care provider, insurance company, or airline is
down
for 4 hours, it could be disastrous.
Clouds aren’t all they’re cracked up to be.
