As someone who has built out over 30 different accounts in AWS for various clients, this is definitely not entirely accurate. Elasticache is a caching mechanism

As someone who has built out over 30 different accounts in AWS for various clients, this is definitely not entirely accurate. Elasticache is a caching mechanism not a database. Anyone who thinks they are the same has not used them extensively. Also RDS and Aurora both have had their super privileges removed so you might have to possibly overhaul some of your code base just to make it work. I’m sensing some uninformed fan base propaganda here
