Despite a perceived bias that mainframes are behemoths that are costly to run and unreliable, the findings also revealed that more than nine in 10 respondents have an overall positive attitude about mainframe computing.
The project conducted the survey to better understand use of mainframes in general. “If you have this amazing technology, with literally the fastest commercial CPUs on the planet, what are some of the barriers?” said John Mertic, director of program management for the foundation and Open Mainframe Project. “The driver was, there wasn’t any hard data around trends on the mainframe.”
