When you really get down to it both AIX and Linux are just different
versions of UNIX. Our AIX machines are every bit as powerful as the
mainframe we migrated off of a decade ago. So Linux on a mainframe
makes perfect sense if you want to run a UNIX style system and the cost
of Linux is less than other available operating systems.
IBM is now trying to sell by service units and Java is expensive to run under this pricing method; however, IBM sells for a very reasonable sum Java co-processing units that remove the Java processing from the billing. Since the underlying concept of Java is write once run anywhere the ability to run Java on a mainframe makes perfect sense. Whether it is the best tool for the job at hand is a different question since most code written on a mainframe will ever run anywhere but on the mainframe. But then again if your shop has mainframes, midrange servers, and PC's to support the ability to have the programmers write in Java on all three platforms instead of Visual Basic on the PC, C on the Unix servers, and COBOL on the mainframe can be a real benefit.
