Linux Magazine’s Top 20 Companies to Watch in 2007

We pick the companies that are defining the future of Information Technology and will have the most impact on the Open Enterprises of 2007. It's the inaugural edition of our 20 Companies to Watch list and we guarantee that every company here will challenge how you think about Linux and Open Source before the year is out.


Some platforms, applications, or companies are worth watching because of what they’ve done in the past year or so, but others are in the spotlight mainly because of the tremendous growth potential that keeps them zipping through the Internet blog buzz. XenSource falls in the latter category, leading many to believe it’s poised to make it big in the year ahead.

Founded and run by the original Xen development team, XenSource is both the centerpoint for the Xen community as well as the sales force that touts the benefits of Xen to enterprises. The group dedicates a significant amount of engineering resources to developing open source technology and making sure that they can back up the claim that the Xen hypervisor is “the world’s fastest and most secure.”

The company is trying to get more exposure though efforts like joining the Interop Vendor Alliance, the high-profile vendor think tank that launched with Microsoft at the controls. XenSource, and others like AMD, NEC, and Novell, hope the IVA will boost interoperability among different platforms and Microsoft Windows.

This isn’t the first go-round with Microsoft for XenSource. Last July, the two companies noted that they’ll cooperate on the development of technology that will provide interoperability between Xen-enabled Linux and the new Windows hypervisor technology-based Windows Server virtualization.

A brief difference of opinions between Novell and Red Hat last year did cause XenSource to lose a bit of shine: Novell began shipping Xen with version 10 of its SUSE Linux Enterprise Server, but Red Hat balked, saying the software wasn’t ready for enterprises yet. But that didn’t stop the company from saying it would try to build a full virtualization platform around the product in RHEL 5, even though it doesn’t yet appear in the beta version.
