John Galt, Chief Innovation Officer and CEO of Atlas Slouches and Blockheads has a great idea. He proposes that the company adopt a "best of breed" approach to hardware and software. That is, use the best hardware and the best software regardless of company or design. Therefore, forexample, he proposes using, for the core transaction processing of the company, the Apple iOS with Deep Blue, the supercomputer designed by IBM. Please comment on Mr. Galt's idea.
•This is a question that is better answered by a IT professional. •Operating systems are designed to run on specific hardware and computers. •It may be possible to "emulate" "foreign" software on hardware but it may not run as efficiently as "native" operating system software. •It is likely to be very difficult and inefficient to try and run an Apple iOS on an IBM supercomputer. (Won't work) •While there may be applications in which this is desirable it is not realistic as a core transaction processing system. Attempting to do so would challenging and would yield dubious benefits.
