There are a lot of flavors of Linux on the market, each with its own unique features and quirks. Businesses are usually willing to pony up for one of the “Big Two”: Red Hat or Novell/Suse. Regular folks, on the other hand, are more likely to download one of the free alternatives.
I’m not surprised at all. Linux runs on tiny phone to large server systems. According to IDC researchers (prediction) – spending on the Linux ecosystem will rise from $21 billion in 2007 to more than $49 billion in 2011, driven by rising enterprise deployments of Linux server operating systems.
Linux server deployments are expanding from infrastructure-oriented applications to more commercially oriented database and enterprise resource-planning workloads “that historically have been the domain of Microsoft Windows and Unix,” noted IDC analysts in a white paper commissioned by the nonprofit Linux Foundation.
“The early adoption of Linux was dominated by infrastructure-oriented workloads, often taking over those workloads from an aging Unix server or Windows NT 4.0 server that was being replaced,” according to the report’s authors, Al Gillen, Elaina Stergiades and Brett Waldman. These days, however, Linux is increasingly being “viewed as a solution for wider and more critical business deployments.”

Red Hat has open-sourced its identity-management and security system to promote its assertion that open-source software provides the most secure infrastructure. From the press release:
Red Hat Certificate System was acquired from AOL three years ago as part of the Netscape technology acquisition. In keeping with our commitment to open source software, today Red Hat has released all of the source code to Red Hat Certificate System. Much of the technology in Red Hat Certificate System was already open source, including the Apache web server, Red Hat Directory Server and the FIPS140-2 level 2 validated NSS cryptographic libraries, but todayâ€™s move further demonstrates Red Hatâ€™s belief that the open source development model creates more secure software.
I think the freeIPA project is really good addition. It provides central management of identity, policy, and auditing for Unix and Linux using open-source and open-standards technologies.
