Cloud data storage platform is a more accurate description.
Consider the audience here. If they aren’t technical this may confuse people more. Especially because Snowflake can frontend on-prem data sources too, not just public Cloud. Unless you’re also using “Cloud” to refer to “Private cloud” which is usually an on-prem deployment, which is yet more confusion for a non-technical audience.
I was using a simple approachable description so people could differentiate that we’re not talking about a slang for a type of human behavior.
