The death of the mainframe has been predicted many times over the years but it has prevailed because it has been overhauled time and again. Now Steve Lohr reports that IBM has just released the z13, a new mainframe engineered to cope with the huge volume of data and transactions generated by people using smartphones and tablets. “This is a mainframe for the mobile digital economy,” says Tom Rosamilia. “It’s a computer for the bow wave of mobile transactions coming our way.” IBM claims the z13 mainframe is the first system able to process 2.5 billion transactions a day and has a host of technical improvements over its predecessor, including three times the memory, faster processing and greater data-handling capability. IBM spent $1 billion to develop the z13, and that research generated 500 new patents, including some for encryption intended to improve the security of mobile computing. Much of the new technology is designed for real-time analysis in business. For example, the mainframe system can allow automated fraud prevention while a purchase is being made on a smartphone. Another example would be providing shoppers with personalized offers while they are in a store, by tracking their locations and tapping data on their preferences, mainly from their previous buying patterns at that retailer.

IBM brings out a new mainframe about every three years, and the success of this one is critical to the company’s business. Mainframes alone account for only about 3 percent of IBM’s sales. But when mainframe-related software, services, and storage are included, the business as a whole contributes 25 percent of IBM’s revenue and 35 percent of its operating profit. Ronald J. Peri, chief executive of Radixx International was an early advocate in the 1980s of moving off mainframes and onto networks of personal computers. Today Peri is shifting the back-end computing engine in the Radixx data center from a cluster of industry-standard servers to a new IBM mainframe and estimates the total cost of ownership including hardware, software, and labor will be 50 percent less with a mainframe. “We kind of rediscovered the mainframe,” says Peri.

    You ---do--- ---not--- want to get into mainframes. Too many unemployed people with 20+ years' experience. Forget being hired as an entry level person. People with experience can't even find jobs. It's a race to the bottom. Not much development is being done on mainframes these days. Maintenance work and stuff, but very little of it, and there's a glut of people with 20+ years of CICS programming experience. In terms of systems programming, mainframes don't require much care and feeding these days. A lot of the systems programming stuff of yesterday is now automated. So there's not much demand for people who know how to configure and keep mainframes running. There's a lot of mainframe outsourcing going on today. One company can run umpteen different mainframes with a small staff. Trust me on this one, run away from mainframes as fast as you can and never look back.

    Thanks for the input, folks.

    I remembered being pretty impressed by a system called Linux/390 (I think) about fifteen years ago. It seemed crazy and powerful at the time, but I'm guessing that whole mess is generally a dead end.

    Appreciate being brought back to earth :D

      If you hadn't asked the question, I might have. That means that there's at least two people on here appreciate of the answers.

      TL;DR: Thank for the question and answers.

      IBM chases fads. Right now, they're chasing mobile transactions for some reason. A few years ago, they were chasing virtualization when it was big. They ported Linux to the mainframe architecture and got it running under VM, their virtual machine manager. (It's like VirtualBox, without an easy to use interface, easy configuration, or anything that would make it easy to use. Imagine a lot of little tables mapping actual hardware to virtual hardware and a bizarre shell-like scripting environment that actually has commands that have start parens with no close parens. It's that awful.) The idea was you could run a bazillion Linux instances on your mainframe. Well, the whole effort went nowhere because people wanted cloud computing, and didn't want their own mainframes. They wanted instances on demand without managing hardware. And a nice web interface for management. (As a bonus, with mainframe Linux, you had to port any code you had to the mainframe architecture, unless it was Java or something.)

      Believe it or not, the mainframe is POSIX compliant and has what they call Unix Systems Services, a complete shell and utilities. The environment is called OMVS. The motivation was to be able to run TCP/IP style servers easily, and run Java and Websphere on the mainframe. OMVS has been much more successful than virtualized Linux. Most of the systems programming stuff comes via OMVS now. In fact, you basically can't even run a mainframe without OMVS active, because the networking support has hooks deep into OMVS.
