Id second the s3 idea as youre hosting data for professional reasons. Backblaze and cloudflare also offer s3 compatible storage, when i priced them up for work cloudflare was by far the cheaper option. But iirc their s3 api is still under development and is not ( at the time i used it) feature complete. We had some trouble generating pre-signed urls. But if you just want some place to store data these are worth a look
Ive worked a couple fortune 500s that used ubuntu. If im using aws ill stick with their distro but most of time im happy with ubuntu. I think distro choice matters less and less. Most of the systems ive run recently have had ansible to configure them or have just run docker containers. Most of the gov contracts iveworked on insisted on red hat but honestly the teams making those decsions seemed the least technically capeable ive worked with and it was just a red tape issue to change distros
Its a simpsons joke
