Mainframe Excellence 2025


Wbrew pozorom i plotkom sprzed roku 2000 mainframe ma sie nie tylko dobrze, ale caly czas sie rozwija.

W zalaczeniu link do „najnowszej plotki”, ktora przewiduje rozwoj mainframe’a na najblizsze 10 lat (conajmniej).




This is an interesting article about the current and future state of the Mainframe. Definitely worth the read for those working on the mainframe and also for those that don’t.

The author is Chris O’Malley.


Chris O’Malley: He is the CEO of Compuware. With nearly 30 years of IT experience, he is deeply committed to leading Compuware’s transformation into the “mainframe software company for the next 50 years.” His past positions include CEO of VelociData, CEO of Nimsoft, EVP of CA’s Cloud Products & Solutions and EVP/GM of CA’s Mainframe business unit, where he led the successful transformation of that division.


The article is a little longer than most but he makes some interesting observations that I think are worth the read. I pulled a few highlights and added them below.

The first was surprising to me and the last will get a good chuckle out of some.


The article link is at the bottom of this email but is also attached in a pdf. The article is on pages 18-31 in the pdf.


  • Despite rumors to the contrary, the world still runs on mainframes. More than 220 billion lines of mainframe application code are in use today, and five billion more are added every year.
    Over 1.15 million CICS transactions are executed on System z every second of every day.
    That’s more than all Google searches, YouTube views, Facebook likes and Twitter tweets combined.
  • And the mainframe cannot be simply imagined away. Studies confirm that most large enterprises expect to continue relying on their mainframes for at least another 10 years—and that their economic value will extend well beyond 2025.
    This longevity is no accident. No other platform or set of platforms comes close to delivering the performance, scalability, reliability or security of the mainframe. None offers a lower marginal cost. Nor has any other platform come close to demonstrating a similar ability to adapt to the changes in the world around it decade after decade.
  • The mainframe platform is not only unique technically. It is also unique culturally. This culture is characterized by a rigorous adherence to a standard of excellence demonstrably higher than that associated with other platforms. IT organizations actually expect and plan for problems and patches in other platforms.
    Mainframe applications and system programmers, on the other hand, expect and demand perfection

  1. Maciek,
    Czy masz jakieś informacje na temat złego stanu mainframe, którymi chciałbyś się z nami podzielić?

    1. Informacje nie sa nowe. Od mniej wiecej 10 lat pracuje w finansach gdzie systemami pisanymi przez nas zastepujemy te z mainframe’a. Koledzy mainframeowcy po prostu przekazuja informacje o funkcjach kolegom z Java i .NET po czym ustalane sa daty kiedy mainframe ma byc zamkniety a rusza projekt systemu w nowszej technologii. Prosta przyczyna – koszt i to nie ten procesora tylko sily roboczej by to utrzymac. Nikt dzis raczej sie nie uczy mainframe’a.
