Here's a new hot topic from IBM in 2024:

As a rule of thumb, if there's something in computing you've heard about, expect IBM to also have heard about it and made something like it for their machines. Sometimes they lag a bit but eventually they converge towards having their own of all things computational.

Think of them as say, your AWS. Except that you can just start randomly replacing hardware without the software skipping a beat. That’s the level of redundancy and stability these things offer.

I didn’t know this either until I started just researching a while back. It’s amazing. They get a bad rep, but they are very very awesome and modern.
