Generating keypairs on a cloud server is a bad idea, security-wise. Usually you would want to keep your private keys as secure as possible!

I just read a [blog](https://0day.work/using-an-aws-gpu-instance-to-generate-vanity-bitcoin-addresses/) about someone rent an AWS hpc & run Vanitygen to get a vanity address & some of the [latest 2018 performance](https://www.reddit.com/r/btc/comments/9aqu7m/use_of_vanitygen_to_try_to_attack_addresses/).
