Recently I got a question on how to find boot volumes of AWS instances. While I did not get any background on the purpose of this, I found the task interesting enough to dig a bit deeper. As in “down to the binary level”. Interested?
When you start out learning about S3, the experts and documentation will tell you that you should think of S3 as a flat key-value store that doesn’t have any hierarchical structure. Then you go ahead and create your first S3 bucket in the console, and what the interface shows you is a nice big “Create Folder” button. You may be justifiably confused - didn’t I just learn that there are no folders, directories, or hierarchy in S3?
