And Google seems especially bad at it.
I learned this recently and thought I'd share! From https://en.m.wikipedia.org/wiki/Amazon_Redshift
* BigQuery vs BigTable (though, there are at least some hints in these)
* Cloud Storage vs Filestore vs Datastore vs Firestore (vs Firebase? How are these related?)
I can of course make an effort to keep these straight, but then having to clarify in every design convo because my manager can't, or having a hard time googling (lol) things germane to the product I'm on, etc, is just a huge hassle.
