I may need some ideas for a personal project in mind:
I plan to have a server that shall connect to a usb stick/device, the usb is plugged to a TV. The usb device can create its own local wifi network which provides CRUD on media files via REST. My own server should be accessible via the internet, but at the same time connect to the local usb wifi, once the usb wifi is available, and then send requests to it. Kind of a user-friendly bridge.
There's a PC near the device, almost always turned on. It's used by family members as regular office machine and could run a local server. What if as remotely accessible server? Then what about DOS attacks? (Would that "kill" the PC?)
An alternative would be a separate server. A raspberry pi? A dedicated server?
