My guess is $10-20 / month for an anemic VM that runs like a raspberry pi.
That's great but considering most ISPs in the US are still < 100Mbit on the download and cap the upload at something ridiculous like 10Mbit, 10Gbps on the server side isn't going to be much use.
Even my workplace caps at around 100Mbps upload meaning uploading a 64GB video off an SD card to my "cloud PC" will take forever.
