Who do you use for your VPS provider? Those specs for that price are much better than what I typically see price wise on DigitalOcean, Linode, Vultr, AWS, etc.

I ignore docker myself. It's been too unstable for me and historically just costs me time, I'd rather just use systemd on a VPS. Occasionally when someone else has setup a complex system in docker I want to play with it has been convenient. Still, I avoid installing it at all.
