I mention in the Linux space only because it's what I'm familiar with and didn't want to make assumptions about groups I'm not familiar with. Unlike you who's looking for a way to take umbridge and talk passed people. I went to college for IT and have done it for 30 years.

In network and IT planning. The cloud is the wider network outside your own. That you don't have mapped. Often depicted by a "cloud". If I have a personal data pool on one of my own networks. And need it from another. It may transmit via the "cloud". But it isn't IN the cloud. It's on a personal server. If the server is in your house, and you can point exactly to where your data is. Then the rule of thumb is that it is in your house. Not the cloud. If it's hosted on a system you couldn't directly point to on a network you have no knowledge of. Especially a shared system. Then things literally and figuratively are getting cloudier.

That said, marketing as it often does. Appropriates and misuses words based around buzz. And I am not about to admonish hobbyist who use it in the marketing sense. I understand, I get it.

If you host in OSX on Apple Silicon, that's great. If you host on a 68k Mac or Amiga you're a fucking mad lad! If you're hosting under Windows, any TCP port in the storm mate. If you are hosting from a Linux distribution that is not God's chosen, cool how is it working out? If you are hosting from BeOS. or Haiku, you are a glorious oddball and absolutely my sort of person. And if you are hosting from an appliance that you really don't know what it's running, welcome to the hobby. It's a good starting point. And a lill data in the cloud isn't a crime. We all have some. But if you can't easily point to it. Can you really know you have it?
