AWS offers a LOT of services. Seeing the list of AWS services in the console can feel completely overwhelming the first few times. Just reading through the names of all services takes minutes. Finding out what every single one does would need a lot more effort. And why would you? If you are like most people, there’s only a small subset of services which you really want to know about. Some of them because they are essential, and some because they come in really handy in specific situations.
