The mainframe computer is not quite going the way of the dinosaur. Even in today’s age of Intel-based servers, there’s still room and relevance for the mainframe. This explains why IBM has launched the z15, its 15th generation of the mainframe.
Remember the mainframe? It used to rule the world of computing and was presumed by some to be extinct when the advent of Intel-based servers and GPU-powered supercomputers. Presumed is the key word here because the mainframe is still alive and kicking though it does not command the clout that it did in the past.
