I happen to read Guide to Key Comparisons of Linux vs. Windows Servers over at work.com and thought it was worth pointing out to those who might not be that familiar with the fundamental differences between Windows and Linux Web server environments.
Because this it’s such a common misconception I should mention first that running Windows or Linux on your Web server has no relationship to the operating systems you and your site users are running on their personal system. Individual computers running Windows or Mac OS Xand and using common Web browsers don’t care what operating system the Web server is running on.
Here highlights I took from the article:
- Both Windows and Linux are about equal when it comes to market share, reliability, performance and security.
- Because Windows is proprietary commercial software and Linux is open source software, if your business decides to own and operate your own Web servers, Windows can be more costly. However, this base cost is nominal if you choose to outsource your Web server hosting and management.
- Linux offers the inherit advantages of open source . . . in terms of flexibility and customization. The author states:
Linux distributors, using an open-source application with more flexibility, can implement “extensible” packages with greater customizability. In normal situations, the performance of the two is comparable, but if system functionality is most important to you, this may have an impact on your final decision.
Another critical consideration that wasn’t mentioned in this article is total cost of ownership. Linux is generally regarded as the leader in this category, but not necessarily, it all depends on each organization’s goals and required applications. Researching total cost of ownership can be confusing . . . since many of the most popular studies are drawing data mostly from very large IT enterprises and in very large enterprises TCO tends to level out between Windows and Linux.
As a general rule the smaller the organization, the more clear-cut are the TCO benefits of Linux over Windows. This does not imply that Linux will not be the best choice for the largest enterprise environments (examples of Linux enterprises include the city of Los Angeles, NASA, Amazon, American Fidelity Assurance Company and Overstock.com), but what it does mean is that any business should spend the time to evaluate the options in light of their specific needs to get the right answer.
