This. I'm presently running serverless containers, serverless jobs, managed container registry, managed database, virtual private network, IAM policies, DNS, managed Grafana and object storage on Scaleway for a project I'm working on. Doesn't get more cloud than that.

Sure, Scaleway still lags behind the big three cloud providers in the US. But the US providers have a lot more money and been around much longer. Scaleway is quickly expanding its feature set though. They've recently introduced managed Clickhouse and OpenSearch among other things.

Hetzner for sure?

Hetzner Cloud is simple to use, but it's a distinguishing feature, not a bug.

I think in order to call youself a cloud you must offer blob storage, managed Kubernetes, and managed Postgres. That is the absolute minimum to me.
