much, much worse
Yes I agree, given the direction G has been going. I was disappointed at the time, but it was probably a blessing in disguise

Red Hat OpenShift (IBM) is what a lot of banks have settled on. Red Hat went all in maybe 5+ years ago in capturing those institutions.
AIX for ARM? ;-)
Is modern ARM stuff done big-endian? because AIX is exclusively BE iirc

Are you guys sure you're not confusing product lines? PPC is a PowerISA architecture, but hasn't been pushing desktop/server level performance for, what, almost 20 years? It's an embedded chip now, and AFAIK IBM doesn't even make them any more. Power (currently "10th gen"(-ish)) is the performant aarchitecture, used in the computers formally known as i-Series, formerly known as RS/6000. It's pretty fast, not not pric…
"PowerPC" was a modification of the original IBM POWER ISA, which was made in cooperation by IBM, Motorola and Apple. Motorola made CPUs with this ISA. Apple used CPUs with this ISA, some made by IBM and some made by Motorola. While Motorola and Apple used the name "PowerPC", IBM continued to use the original name "POWER" for its server and workstation CPUs. Later IBM sold its division that made CPUs for embedded app…

Early in my career I spent some years working at the biggest bank in Canada, they were (and still are) an enormous IBM customer. Hardware, software, consulting, and probably lots of other things I had no visibility into. Beneath the countless layers of VMs and copious weird purpose built gear like Tandem and Base24 for the ATMs was a whole bunch of true blue z/OS powered IBM mainframes chugging through thousands and…
I don't how exaggerated this story is, but one of my buddies did his internship at TD. One of his skip managers told him if you know COBOL there are departments that will give you a blank cheque during salary ngotiation.

They design and build not one but two CPU architectures, s390/Z and POWER. Both have been around for many years, but neither is obsolete, they're just not designed for consumer applications. They still generate $10-15 billion per year in revenue.
Power was used in customer applications a long time ago? I think Apple used them for a while and so did some game consoles?

This is a serious question. What does IBM, in fact, do? I'm surprised they are still around and apparently relevant. Are they more or less a services and consulting company now?

But I wonder if this is "much better" than x86 emulation or virt? Is there really SW that's limited to (Linux) ARM and not x86?
Technically aren't most android apps limited to ARM?
I'd guess most apps are bytecode only, which will run on any platform. Some apps with native code have bytecode fallbacks. Many apps with native code include multiple support for multiple architectures; the app developer will pick what they think is relevant for their users, but mips and x86 are options. There were production x86 androids for a few years, some of those might still be in user bases; mips got taken out of the Native Development Kit in 2018 so probably not very relevant anymore.

> Credit card transactions and banking software run on this model for example Eh, they can but even a couple of decades ago there was a shift to open platforms. 90s and early 00s, sure, it was mainframe and exotic x86 species like Stratus machines. But even then the power of “throw a ton of cheaper Unix at it” was winning. Banks’ central systems maybe, I have less experience there. IBM did also try for a while to rid…
x86 servers weren't that common in the 90s and early 200s, that was all sun or the other commercial unix peoples things
