The scenario of having open-source technology in a product is a first for Microsoft, which to date has had only proprietary technology in its software, said Robert Duffner, a senior director in Microsoft's Platform Strategy Group.
Letting the acquired technology exist as it is, and letting the former Powerset employees continue to contribute code to Hadoop, represents a shift in mindset and strategy at the company to be more friendly toward open-source technology and realize that "innovation occurs across a wide variety of technologies," he said.
In addition to the Powerset code, Microsoft also for the first time in 2008 began contributing other code to open-source projects. In July, Microsoft began providing code to a PHP project called ADOdb. PHP is an open-source, freely available scripting language that developers widely use for Web development.
Duffner's group, under the direction of Microsoft Senior Director Sam Ramji, is driving this movement to not only accept open-source software as a technology with which Microsoft's software has to interoperate effectively, but also to see it as beneficial to both Microsoft's own business goals and the industry as a whole.
Having long positioned Windows and other proprietary software against open source as "us versus them," Microsoft is now trying to convince customers that the two technologies are not mutually exclusive and in fact can even be complementary at times.
