Assume I have a physical server with vanilla Ubuntu Server 18.04 LTS where I'll do some minimal configuration adjustments in
/etc/ssh/sshd_config and only install
Using docker I'll be running whatever workloads I need to run and I'll be keeping the host up to date regularly via these commands:
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo reboot now sudo apt-get autoremove
Should I prefer something other than Ubuntu (e.g Debian, Arch, CentOS) because it'll offer me better performance or better security? Or will sticking to Ubuntu offer me exactly the same performance and security as anything else for my usage scenario?
Edit: I do not care about how large the host O/S is on the server. I'm only looking into facts and figures which confirm whether performance and security are affected.
