Infrastructure diversity is one important component of many IT infrastructures’ complexity. Even at a time when organizations are standardizing on x86 hardware, they often maintain separate support groups by types of operating systems. In the meantime, we see even more technology diversity developing in a relentless pursuit of performance, and ironically, simplification. This begs a simple question: Should we, for the sake of operational efficiency, standardize at the lowest possible level, e.g., the computing platform, or at a much higher level, e.g., the user interface?
In the past months, I think a clear answer was provided by the mainframe world. One key element that actually limits mainframe expansion in some data centers is the perception from higher levels of management that the mainframe is a complex-to-operate and obsolete platform, too radically different from the Linux and Windows operating systems. This comes from the fact that most mainframe management solutions use an explicit interface for configuration and deployment that requires a detailed knowledge of the mainframe specificity. Mastering it requires skills and experience that unfortunately do not seem to be taught in most computer science classes. Because mainframe education is lacking, the issue seems to be more acute than in other IT segments. This eventually would condemn the mainframe when all the baby boomers decide that they would rather golf in Florida.
This whole perception was shattered to pieces by two major announcements. The most recent one is the new IBM zEnterprise platform, which regroups a mix of hardware and software platforms under a single administration interface. In doing this, IBM provides a solution that actually abstracts the platforms’ diversity and removes the need for different administrators versed in the vagaries of the different operating systems.
