In this day and age of cloud computing, this article’s headline may come as a bit of a shock to many of you. Yes, the mainframe is still a thing. And IBM’s newest is a beast of a machine, capable of over 2.5 billion transactions a day, with real-time encryption built in.

Operating in the background, mainframes are critical to activities including banking, online and in-store shopping, purchasing car insurance, booking travel, registering for university classes, registering a motor vehicle, obtaining a driving license, filing taxes (whether with the IRS in the US, HMRC in the UK, or Bundeszentralamt für Steuern in Germany), and yes, even talking on the phone, whether mobile or fixed.
