> I think you're conflating "cloud" to mean any computer on the internet.

If you read "cloud" as "somebody else's computer" it entirely depends on perspective.

If you're running a service on your own hardware in your own datacenter, you're clearly not cloud.

However, if you're a user of that same service, and your data lives on some computers that are running in someone else's data center, then for all intents and purposes your data is "in the cloud". It's indistinguishable if the service you're using is using AWS/Azure/etc, running their own hardware, and/or storing data on something like S3.

There's of course a mix of in between stuff that makes this 10x more complicated: if it's a rented server in somebody else's datacenter, are you "cloud" or not? What if it's your hardware, but somebody else's datacenter? What if you store backups on S3?
