I get that Lightsail isn't intuitive, but what could be more simpler or easier to comprehend than Relational Database Service or Simple Storage Service?

Nobody calls those products by their expanded names though. Why not just AWS Storage or AWS Database?

Google for example has Google Cloud Storage and Google Cloud SQL. I get that it becomes trickier when you've got overlapping products but you can't even guess the domain of AWS products from the name they're so obtuse.
