Enterprise Linux Slippage
企业级Linux的下滑 The growth in use of generic Linux appears to have come somewhat at the expense of the leading enterprise Linux distributions: Red Hat (NYSE: RHT) Enterprise Linux (RHEL) and Suse Linux Enterprise Server (SLES). In various versions, both distributions of Linux lost ground from the June 2010 Top500 list compared to this year's. For SLES, which continues to garner enterprise use and credibility despite some uncertainty from its Attachmate acquisition, the OS slipped from a total of 38 systems to 34 on the latest list. In addition, I should point out that despite its No. 2 position in the enterprise server market, SLES has long been the leading Linux distribution and individual OS on the Top500 list. As for RHEL, its representation in nine supercomputing systems in 2010 dropped down to six systems in the latest list. I should also point out there is certainly representation of both RHEL and SLES, as well as their community cousins Fedora and OpenSUSE, in the generic Linux category of the Top500 list, which represents 82.6 percent of the systems. CentOS is increasingly identified as a top choice for supercomputing systems, though the RHEL clone slipped from seven spots on the Top500 list last year to six spots this year. The latest Top500 list reinforces some of the changes in the Linux market that we are currently observing, driven primarily by cloud computing, the confluence of application development and deployment, or devops, and the ongoing impact of unpaid, community Linux. We continue to track these changes and encourage users to weigh in via our brief survey here. |
