The server is the machine, from e.g dell, or a virtual machine subdividing a real piece of equipment
The webserver is a piece of software it runs that responds mostly to HTTP requests. e.g Apache, Nginx, Traefik, Caddy.
All webservers are running on a server. Not all servers run webserver software, they might be a fileserver running samba or nfs.
not real linux, so no native docker development.
Also the UI of the OS is turbo liquid ass.
I'm being forced into it by my employer.
