Difference between IIS and Apache Web Servers

When it comes to web servers, IIS and Apache are two popular choices. Here are some key differences between the two:

• Operating System: IIS is developed by Microsoft and primarily runs on Windows operating systems, while Apache is open-source and can run on various operating systems including Windows, Linux, and Unix.
• Performance: Apache is known for its flexibility and scalability, making it a popular choice for handling high-traffic websites. On the other hand, IIS is often preferred for its integration with other Microsoft products and services.
• Configuration: Apache uses configuration files (httpd.conf) that are typically more flexible and customizable, while IIS relies on a graphical user interface for configuration settings.
• Extensions and Modules: Apache has a wide range of extensions and modules available, providing additional features and functionality. IIS also supports extensions, but the selection may be more limited compared to Apache.
• Market Share: Apache has historically been more widely used and has a larger market share compared to IIS. However, IIS has gained popularity in recent years, especially in corporate environments.

Overall, the choice between IIS and Apache depends on the specific requirements of the website or application being hosted. Both servers have their own strengths and weaknesses, so it's important to consider factors such as operating system compatibility, performance needs, and ease of configuration before making a decision.
