But the market for UNIX\u2122 machines is<\/em> a great deal smaller than it used to be. And why is that? I would argue that whilst Linux made the transition easier, it isn’t the real reason why many organisations swapped out their high-priced machines for cheaper machines. <\/p>\n\n\n\n And that gives a bit of a clue. Whilst the high-priced machines from Sun, SGI, HP, IBM, Digital, etc. weren’t over-priced<\/em> they were expensive. The hardware was built to be exceptionally reliable – for example some of the Suns I worked with could deal with a processor failure by simply turning off that processor and letting an engineer replace the board all whilst the system was up and running. <\/p>\n\n\n\n No what “killed” those expensive UNIX\u2122 machines was virtualisation and the use of commodity hardware. If a modern server dies, the virtual servers running on it are simply migrated to a working server suffering at worst a reboot (but probably not). <\/p>\n\n\n\n Plus there was a realisation that not everything needed to be continually available.<\/p>\n\n\n\n Just seen a video title about how Linux defeated UNIX\u2122; it is quite hard to dispute this givennd that that Linux is alive, well, and thriving. But I would argue that it isn’t quite true. First of all, UNIX\u2122 is technically alive as Solaris, HP-UX and AIX are still active.
