In an article I read recently by Ian Bramley from Mainframe Executive Magazine, several advantages were put forth on why you should consider moving to or staying on mainframe applications. Many of these dealt with downtime and security, which I’ll capitulate that the mainframe environ does better with. I do believe, however, that the high cost of the mainframe and the required training to operate one are responsible for a large part of these advantages, but I’ll talk about that at another time.
The article starting me reminiscing about my own mainframe and mini-frame days. What is more interesting to me than the differences between now and then are the similarities. When Personal Computers (PC’s) were introduced, no one thought that they would work as servers someday. Multitasking operating systems were restricted to UNIX and it’s derivatives, and no one thought about things like virtualization, SAN fabrics and the myriad of other things we routinely deal with now, our “grown up” PC’s.
Isn’t it interesting that the more things change, the more they stay the same?
