I hesitate to call Hetzner "cloud". Hetzner is an EC2+S3 competitor, not an AWS one. IMO the minimum for being a real cloud is you need hosted Postgres, hosted Kafka, hosted Kubernetes, and S3-compatible object storage. Without the first three Hetzner is just not in the same product category. Nobody sensible buys AWS for the comically overpriced EC2.
Is it really so much cheaper to pay for "hosted" apps rather than just plumbing your own on VPS/metal?
Another missed component is a real autoscaling load balancer. This often gets missed and taken for granted. Possibly due to if you haven't seen a good one (AWS) you might not realise what you're missing. Most aspiring "cloud" companies have fixed capacity single tennant load balancers which is not cloud in any definition.
