About

Microsoft Internet Information Services (IIS) is an extensible web server developed by Microsoft for Windows systems.

It has a modular architecture with standalone components, supports HTTP, HTTP/2, HTTP/3, HTTPS, FTP, FTPS, SMTP, and NNTP protocols, enables worker process isolation through application pools, and provides native integration with ASP.NET and ASP.NET Core.

Nginx is a lightweight, high-performance open-source HTTP server and reverse proxy.

It supports serving static files, HTTP/2 and HTTP/3, SSL/TLS termination with SNI, proxying and load balancing for HTTP, TCP and UDP traffic, and caching of FastCGI/uwsgi/memcached responses.
