Analyst(s): Richard Jones

Summary

The two leading enterprise Linux server operating system distribution vendors have released their next major revisions. Novell's SUSE Linux Enterprise Server 11 Service Pack 1 and Red Hat's Red Hat Enterprise Linux 6 both represent the latest hardened and maintained Linux operating systems that the Linux community has to offer: systems that continue to close the gap on proprietary Unix in supporting mission-critical scalable workloads. Though many features and functions continue to converge between the two vendors' products, the vendors' strategies for virtualization and cloud have diverged.
