Security Innovation Finds Microsoft Windows Platform More Reliable Than Linux

Reduced IT Complexity Yields Greater Reliability for Companies Running

Microsoft Windows Platform Compared With Linux

Nov 16, 2005, 00:00 ET from Microsoft Corp.

    BARCELONA, Spain, Nov. 16 /PRNewswire-FirstCall/ -- Today at the IT Forum
 2005 event in Barcelona, Spain, Microsoft Corp. (Nasdaq:   MSFT) announced
 findings from a report it commissioned from Security Innovation Inc. (SI), a
 leading independent provider of application security services, which concluded
 that as requirements evolved over time, the Microsoft(R) Windows(R) platform
 was more consistent, predictable and easier to manage than Linux. Microsoft
 also announced that industry-leading customers, including Teleflora and Tommy
 Hilfiger Corp., have cited reduced complexity and greater reliability as
 driving their decision to deploy the Microsoft Windows platform over Linux.

     -- Teleflora. A leading provider of technology services to florists,
        Teleflora conducted a two-year study looking at all the various
        offerings from Linux and the IBM Linux stack. Citing scalability and
        better reliability, Teleflora rewrote the entire application using .NET
        deployed on the Windows platform.
     -- Tommy Hilfiger. Citing better manageability and increased reliability,
        international retailer Tommy Hilfiger switched its e-commerce solution
        from Linux to the Windows platform.
     "As they attempt to increase business capabilities over time, customers
 are telling us that they are hitting a wall with Linux, experiencing
 significant reliability issues resulting in higher total cost of ownership,"
 said Martin Taylor, general manager of Platform Strategy at Microsoft. "This
 study shows that IT administrators were better able to maintain the system
 while delivering new capabilities predictably and consistently on the Windows
 platform. We invite other vendors, including Novell, IBM and Red Hat, to
 repeat their own independent analysis based on Security Innovation's
     Security Innovation Puts Reliability to the Test in Real-World Scenario
     To compare reliability and manageability differences between Microsoft
 Windows- and Linux-based solutions, SI delved into the true extent that
 maintenance, patch application and system failures contribute to IT pain and
 cost as business requirements evolve over time. Simulating a real-world
 enterprise e-commerce environment over the course of a year, SI compared two
 teams of experienced IT administrators as they maintained and enhanced on
 Windows Server 2000 and Novell SUSE Enterprise Linux 8, then upgraded to
 Windows Server 2003 and Novell SUSE Enterprise Linux 9, respectively:
     -- The Windows platform was more reliable as enterprise needs change over
        - The Linux administrators took 68 percent longer to implement new
          business requirements than their counterparts.
        - The Novell SLES solution experienced 14 critical breakages while the
          Windows Server solution experienced none.
        - The Novell SLES solution required 4.79 times the number of patches.
     -- The Windows platform was more consistent and predictable.
        - Only one of the three experienced Linux IT administrators
          successfully met all business requirements, while all three Windows
          administrators succeeded in meeting requirements.
     "Our research indicates that the primary methods of computing reliability
 as indicators of real IT pain are overly simplistic. For example, kernel
 uptime is commonly cited as a metric of overall platform reliability. However,
 the reliability of a single component, even one so central as the operating
 system kernel, is rarely the largest source of pain," said Herbert H.
 Thompson, Ph.D., chief security strategist at Security Innovation. "Security
 Innovation designed this study to be repeatable, and we believe that the
 results are consistent with what customers are experiencing in the real

     Customers Cite Greater Reliability on Windows Server 2003
     "One of the things we love about the Microsoft solution is that it allows
 us to deploy a completely integrated solution set. Today with our Linux and
 SCO solutions, we're having to piecemeal and bolt components together," said
 Terry Byers, chief technical officer at Teleflora. "Despite what you hear
 about Linux being able to scale at higher transaction volumes, we're running
 our entire Web portfolio on Windows Server 2003 and have the highest service
 levels we could have in terms of reliability."
     Eric Singleton, chief information officer at Tommy Hilfiger, said, "In a
 way, Linux is now perhaps turning the corner but it's got to get the final
 tier of reliability and predictability that I'm going to bet a multibillion-
 dollar corporation's future on. We expect that consolidation on the Microsoft
 Windows platform across the enterprise will deliver a significant reduction in
 IT costs. However, lower IT costs are only the start. The driving force behind
 all our efforts is an improved competitive advantage. We believe these new
 capabilities will result in an additional return on investment, such as
 compressing product design times and optimization of our supply chain."
