Asked by eWEEK whether this was a representative enough number to draw such conclusions, Rymer said Giga wanted to delve into the details from a smaller number of companies to get enough information to allow it to construct a model to compare Windows and Linux/J2EE. "We also took some guidance from the market as it were. Our interviews with organizations using Linux quickly indicated that J2EE was their development and deployment platform of choice. As such, a J2EE/Linux environment has been used as the basis for comparing a Linux to Windows environment in this study," he said.But Martin Taylor, Microsofts general manager of platform strategy, told eWEEK in an interview on Monday that the company is "in no way extrapolating this out to say that for any small or large operation anywhere in the world that this applies completely to you and that I can guarantee 25 percent savings. Im not saying that at all," he said. However, Giga is a credible third party and by supplying the full report to anyone who wants to see it, Microsoft and Giga are not only giving users the data, but also the process and methodology so they can "do this on their own research and compare their results. Id also love to see a Linux vendor sponsor research that shows a 25 percent savings," Taylor said Rymer said its time for the debate between Microsoft and the open-source community in this regard to move from emotion and religious belief into real, practical consideration. "Thats our business and why we wanted to do this. We really need to take a step back and look at where these choices are going to produce the best advantage for the client. This study does not cover every possible case out there, and thats fine as thats the next thing we can then work on," he said. Next page: Getting Analysts to Understand Red Hat.
He also acknowledged that the studys results are probably a good representation of the middle but not the extreme cases at both the high and low ends.
