performance comparison

In terms of performance, Nginx is a very high-performance reverse proxy server that handles requests in a single-threaded event-driven fashion and can handle thousands of concurrent connections. In contrast, the performance of IIS, although improved, is still not as good as that of Nginx, so if performance is important, it is better to choose Nginx as a reverse proxy server.


location / {
proxy_pass http://backend;
}

Configuration Flexibility

In terms of configuration flexibility, Nginx provides more flexible configuration options that allow complex reverse proxy rules to be implemented with simple commands. At the same time, Nginx's configuration syntax is more intuitive and easy to understand, allowing administrators to configure and adjust more easily. In contrast, IIS configuration is relatively cumbersome and requires more effort to maintain and adjust.

server {
listen 80; server_name example.com; server_name
server_name example.com; server_name { listen 80; server_name example.com; server_name example.com
location / {
proxy_pass http://backend; }
}
}

Operating System Support

In terms of operating system support, Nginx can run on many types of operating systems, including Windows, Linux, Mac OS, etc., and can be migrated across platforms using the same configuration files. In contrast, IIS can only run on Windows operating systems, which is a big limitation for cross-platform support.

In summary, although both IIS and Nginx can be used as reverse proxy servers, Nginx is a more suitable choice as a reverse proxy server in terms of performance, configuration flexibility, and operating system support.
