Since you’ve found your way to Planet Mainframe, you probably know that mainframes are the IT workhorses of big business. It’s not an exaggeration to say that it’s hard to even imagine the past several decades of commerce without the mainframe doing its thing, mostly in the background, processing billions of transactions each day.
