I write this week from IBM’s Insight conference in Las Vegas. A former InfoWorld editor in chief, Stewart Alsop, predicted that the last mainframe would be unplugged in 1996. This week I'll attend a session where IBM runs Apache Spark on a mainframe, even as the mighty beast's luster finally fades.
I'm going to the Spark-on-the-mainframe session for the lolz. IBM loves its mainframes because they sustain one of the few noncompetitive hardware businesses in existence, where IBM can make nearly a 50 percent margin.
