AWS Terms

3 minute read

There are many terms in AWS that use confusing names for simple things. Even working with AWS for over a year, I really miss out on some terms. That’s why I wrote this article. Typing whatever I remember. I am studying these for my AWS exam, which I will take in a few weeks!

So here are the terms:
