Business & Technology in Tennessee - Ep 4 Features John Rockwell, from

IBM is constantly showing the world that it is one of the most innovative providers of technology.  Their legendary IBM i (AS/400, etc.) platform remains one of the most secure and stable systems ever released, and their Power Systems servers are some of today's top performers. However, competitors across the country are trying to convince consumers that IBM is a spent force and that migrating to a rival system is the way to modernize and increase their productivity.

Episode 4 of the InfoSystems podcast series, Business & Technology in Tennessee with Josh Davis, features John Rockwell, Application Developer and owner of the

John Rockwell has partially retired and these days only takes on projects that are close to his heart. One such project is his website.

The purpose of this site is to demonstrate that the IBM i ecosystem remains exceptionally strong. He encourages companies not to abandon their IBM i systems despite the scare tactics of competitors that say only a few organizations use IBM i these days. John says that between 75,000 - 100,000 companies are using IBM i globally, and he has confirmed more than 25,000 in the U.S. alone.

IBM i offers a range of significant benefits over other systems. Security is a major feature along with stability. IBM i uses a proprietary coding language that is not widely known, making their Power Systems almost hacker proof.

IBM works differently from competitors, working from the top down. They have created powerful hardware that is capable of outperforming equivalent systems on the market. They then develop the different pieces to add to this hardware for an enhanced and extended performance.

John Rockwell also uses his website to match companies and RPG programmers. RPG as a programming language is not as widely used as it once was. Millions of lines have been written in RPG for IBM and there are still many companies that use it. For proof, just reference the list on

The difficulty of locating experienced programmers has been seen as a negative for the IBM i platform, and business leaders may not realize just how many RPG programmers are available for work. The website includes a hiring board that lists over 450 available RPG programmers.

Be sure to listen to the podcast for a very interesting discussion about the history of the IBM i platform.
