The Mainframe is a Witch!

The Mainframe Witch-Hunt

The Salem witch trials were an ugly moment in US history. A combination of groupthink, bad religion and confirmation bias led an entire community to act irrationally. And the results were not pretty. Twenty people—most of them women—were executed for being something we know they could not have been.

The mainframe has also been a victim of groupthink, bad religion and confirmation bias. That groupthink centers around the popular but clearly erroneous idea that mainframe is excessively expensive—and that its days are somehow numbered. The bad religion is a dogmatic faith in all things commodity compute. And confirmation bias is a refusal to look objectively at the facts of the matter.

Those facts include:

• Mainframes account for 68% of IT production workloads, but only 6% of IT spend (Source: Solitaire Interglobal)
• Over the past five years, costs at server-intensive IT shops have gone up 65% more than those of mainframe-intensive IT shops. (Source: Rubin Worldwide)
• Mainframe-intensive companies earn 28% more per dollar of IT infrastructure than server-intensive companies. (Source: Rubin Worldwide)
• Between 2005 and 2014, the ratio of mainframe MIPS to mainframe full-time equivalent employees has grown 351%. As a matter of historical significance, never in the history of IT, have so many owed so much to so few, as when it comes to dedicated, long-serving mainframe employees. (Source: Gartner)

In other words, mainframe economics have been proven to be better than distributed computing economics. Not by a little, but by a lot.

The Enlightened CIO

CIOs who don’t suffer from groupthink, bad religion and confirmation bias will recognize the mainframe for what it is: the world’s most powerful, scalable, reliable, secure and resource-efficient platform. The good news is that puts them in position to take unfair advantage of the mainframe’s power and superior economics to achieve things that less-enlightened peers cannot—especially when it comes to supporting technology intense requirements for rapidly growing mobile, transactional, and IoT workloads.

The bad news is that enlightenment doesn’t come without conflict. For one thing, resistance to groupthink requires a certain sort of intellectual backbone. You have to believe what you believe because it’s true—not simply because everyone else believes it. 

For another, you have to invest in the generational transfer of mainframe stewardship. One casualty of the “mainframe witch-hunt” has been the diversion of an entire generation of IT professional away from the world’s most powerful and secure compute platform. So if you’re going to keep leveraging the platform as your veteran mainframe talent heads into retirement, you must transform your mainframe culture and your mainframe toolkit.

Neither of these things comes easy. But if you have a mainframe and the will to fight for what's right, you will be able to do more for less—and with far greater confidence—than those who have been crying “Witch!” for far too many years.
