Maybe your courses were focused on front-end topics like HTML, Javascript, and CSS. The web platform, web hosting, and the Internet infrastructure include a lot of other technologies.
It seems that the technology landscape has gotten complex enough that a lot of people who work with the web have divided themselves into front-end developers and back-end developers, and the back-end developers may be further separated from system administrators or devops engineers.
But I think some curricula are short-changing people by not giving them a useful big picture view of all of these technologies, where they come from, and how they work together.
That being said, what Let's Encrypt aspires to is integration with hosting providers and in server software so that almost all configurations can get, install, and renew certificates automatically, without significant human intervention.
