> I ended up not wanting to put my years of thinking, planning and researching up on a public service, so I spun up a $5/month VPS instance from AWS Lightsail to be a dedicated git server.

So now you are putting all your eggs in one basket and you have the headache of this AWS service and any changes AMZN wants to make to that service.

The beauty of git is that you can have multiple remotes and push to all of those remotes.
