>Or will smaller players go from single-AZ to more expensive multi-AZ?
I... don't think you know what S3 is. Or maybe what FTP is.
(Also S3, EC2, RDS, etc. were named long before GCP had competing services)
All of these make sense.
If you're gonna complain about names, at least pick the really sucky ones, like Athena, Snowball, etc.
