Windows Server Shows more Reliability Than Linux: Study

Windows 2003 Server shows more reliability than Red Hat Enterprise Linux with nearly 20 percent more annual uptime in similar deployment scenarios, said research firm Yankee Group.

According to the results of the firm’s 2006 Global Server Reliability survey, among mainstream server operating systems, only Unix-based server operating systems including HP-UX and Sun Solaris 10 bested Windows Server 2003.

Additional key results for survey show that on average, individual corporate Linux, Windows and Unix servers experience three to five failures per server per year, resulting in 10.0 to 19.5 hours of annual downtime for each server.

In addition, standard Red Hat Enterprise Linux and niche open source vendors gained more outage time compared to Windows or Unix competitors. Yankee Group determined a significant portion of this outage time is attributed to the scarcity of Linux and open source documentation compared to the more mature, established operating systems.

Laura DiDio, Yankee Group Application Infrastructure & Software Platforms research fellow pointed out that all of the server operating system platforms have demonstrated improved reliability, performance and management services. However, he cautioned corporations to adhere to the best practices in training, testing and configuration to ensure optimal server operating system performance and application reliability.
