"Server setup" is a bit vague.

You should start with something less ambitious and less complicated, like running your code on a single machine from e.g. Digital Ocean or linode. Managing a single machine setup is much easier than doing AWS and almost everything you learn will also apply to AWS setup.

AWS is appropriate for large deployments, where your service outgrows the capabilities of a single machine.

I run 2 websites on a single Digital Ocean $10/month server and there's plenty of room for more.
