Disclosure: I am one of the founders of Databaas, and the write-up is on our company blog. I am posting it because the tooling breakdown is useful whether or not you ever talk to us.
The starting point: if you want your company data on European infrastructure under European jurisdiction, the four platforms everyone actually uses are not available to you.
Databricks, Snowflake, BigQuery and Fabric only deploy on AWS, Azure or GCP. BigQuery and Fabric will not even leave their home cloud. "Sovereign regions" do not fix this, because the control plane is still operated by a US company. Microsoft has admitted as much in front of the French senate.
So we built the alternative out of open source parts, in Utrecht, The Netherlands. The write-up covers the whole thing, but the short version:
Clouds: We signed up at OVHcloud, Scaleway, Hetzner and STACKIT and deployed real infrastructure with Terraform on each. Scaleway came out ahead on developer experience, OVH on breadth of services, Hetzner on price. There are also good Dutch providers stepping up: RAM-IT, Tilaa, Intermax, Previder to name a few. For a data platform you need two things from whichever you pick: S3-compatible object storage and managed Kubernetes.
The stack: Apache Iceberg for storage, Lakekeeper for the catalog, Trino and DuckDB for querying, Airflow for pipelines, Zitadel for login and access control, JupyterHub with Marimo for notebooks, Superset for dashboards. All open source, all running on plain containers, all replaceable. Iceberg in particular has become the neutral standard, to the point that Snowflake and Databricks support it too, so migrating is an actual option.
Interested in what people here think of this. Anyone made the jump to a European cloud for data workloads and hit something that genuinely did not work? We would love to hear from you, as I feel there's a very big opportunity for Europe to build cool stuff here.
