Do you want to let people enter text and save it to a database in the cloud? All of these options touch on different infrastructure layers of the web.
There's a data layer. There's a security layer. There's a visual design layer. There's a hypertext layer that links to other locations. There's an authentication layer. There's an algorithmic layer.
Almost all of these layers are completely invisible to “end users” of the web. They just see a flat static page. There is no topography. There is no transparency to how this website is structured or built. You don't know what other websites it's connected it, or where it's pulling data in from. The amount of technical literacy you need to even begin to see these layers is non-trivial.
