Ask HN: Can any Hetzner user please explain your workflow on Hetzner?

I am thinking of trying out Hetzner for hosting front-ends, back-ends. I have some questions about the workflow on Hetzner.

How do you

- deploy from source repo? Terraform?

- keep software up to date? ex: Postgres, OS

- do load balancing? built-in load balancer?

- handle scaling? Terraform?

- automate backups? ex: databases, storage. Do you use provided backups and snapshots?

- maintain security? built-in firewall and DDoS protection?

If there is any open source automation scripts please share.
