On the one hand, open source software can make corporate cooperation, challenge Microsoft and other common enemies, or improve technology to accelerate overall market. But on the other hand, a company is also more difficult to maintain competitive advantage.
Red Hat spokesperson Leigh Day said on Thursday, Enterprise Linux's determination update version is scheduled in September this year.
The new version will also support IBM's new Power5 server and provide new security features.
