Thinking of renaming my "webserver" to "mysql server". Basically it hosts things with something like a traditional LAMP stack (BSD, perl/python/ruby/php, and stuff obviously, and OpenHTTP rather than Apache), rather than web services that back a different thing that a database.
Unifi, Charred, Emby, Homeassistant, Koha hell even my email server all use HTTP for a lot of their lives, but my "web" server is my "web" server.
