I wasn't trying to imply a person needs to have the entire set of domain knowledge before operating a server, but simply researching about what you are attempting to do before just copy-pasting bash lines into your terminal and not even recognizing how it even works at all.

AWS lets you not have to know a great deal about setting up servers and networks, which is great, because they are very skilled at it when they set it up for you. Then, all you need to research is what you need to do/use to deploy your apps.
