The web server contains two levels of hardware and software:

Website server hardware : a computer (physical or virtual) connected to the Internet for storing web pages and web-related files. Most cloud computing companies can provide web server rental services.
Website server software : software used to publish web pages to the outside world, installed on the website server operating system. Web pages can only be accessed by Internet users after being published by the website server software. Nginx, Apache, IIS, etc. are all world-renowned web server software.

Generally speaking, the web servers we buy all include hardware and corresponding software.
