Hmm, this whole article has me a little suspicious. While I get that each OS has its own offerings, I am still not convinced that the way the article below was presented is completely accurate.
Security is one of the chief concerns of IT decision makers. Along with purchase price, interoperability, maintainability and deployment costs, security is a critical factor in determining which platform to deploy across an enterprise or to serve a particular role.
For proprietary and open source software (OSS) alike, administering security updates are a reality in the enterprise and a significant factor in total cost of ownership (TCO). In order to get an accurate picture of how costs associated with patch management figure into the TCO equation, Microsoft recently commissioned Wipro Technologies Ltd., an independent consulting firm, to study the cost of updating Microsoft and open source software in a real-world environment for desktops, servers and database servers.
Wipro surveyed 90 companies in the U.S. and Western Europe with 2,500 to 113,000 employees where both the Windows and open source operating systems were simultaneously being run. When the costs of updating are distributed across the size of the environment and evaluated on a per-asset basis, the study shows Microsoft software to be less expensive to patch than open source equivalents. These findings confirm what many customers are experiencing in their deployment scenarios.

At Chicago-based Cole Taylor Bank, internal analysis showed that Linux costs would be at least 20-percent higher than those in a Windows environment. “Once Microsoft lets us know that a patch exists, we’re able to evaluate them very, very quickly and remotely deploy the patches,” says Manuel Montejano, CIO at Cole Taylor Bank. “It not only keeps our cost down but it keeps our time-to-market very, very short.”
With the specific aim of improving security management, value and reliability, Independence Air, a regional passenger airline based at the Washington-Dulles International Airport, moved its e-commerce Web site from Linux to Microsoft. “We already know how to secure a Windows-based solution and keep it running smoothly,” says Stephen Shaffer, the airline’s director of software systems. “With Linux, we had to rely on consultants to tell us if our system was secure. With Windows, we can depend on Microsoft to inform us of and provide any necessary updates.” [Read the rest]
