John,

it looks like you are on AWS and you selected an AMI, most probably the default one, that offers AWS Linux distribution. It is a downstream of Fedora. We don't support it officially so pick and AMI with Ubuntu and Red hat.

wrt context: you'll find that in general the cloud runs on Linux. You'll get used to automate procedures with scripts and a plethora of tools that are available in the industry like bash, Terraform, Ansible or any config.management tool of your liking.
