Long ago i spent endless days in a booth of a 4GL based software company at the CeBit fair in Hannover. We were selling a database system for developing business applications. I remember that around us there were countless companies selling business software on dedicated IBM hardware called AS400. Now, about 12 years later, Zend got an order from IBM to port PHP to these systems (now called "System i" or "i5"). This is how they cross my ways again. And they are still backwards compatible. I learned that 1 CPW means 1 time the power of the first i5 predecessor machine. Medium sized machines these days have about 11000 CPW. I had done some performance tests and installed some software on i5 machines at the beginning of last year already. Now the next generation of hardware and operating systems come out and provide a many times faster performance.  The i5 will probably not change the way high traffic web applications are deployed today. But since it is present in the backend of a lot of medium sized to big companies it can help PHP into the business critical part of their application landscape. PHP is much easier to learn and much more natural choice for business software programmers than for example Java. Therefore i predict a great future for PHP on i5 in all these medium sized companies. Tired of building CMS and the usual web stuff in PHP? I guess we will get quite some demand for enterprise level business software from this area...
