CloudNativePG: sovereignty score and 8 European alternatives

CloudNativePG is an open-source Kubernetes operator that manages the full lifecycle of a highly available PostgreSQL cluster. It is configured declaratively through the Kubernetes API and uses a primary and standby architecture with native streaming replication, without StatefulSets for storage or an external failover tool. The project is delivered as software installed in a Kubernetes cluster, so the organisation runs its databases itself rather than buying a hosted service.

CloudNativePG is released under the Apache 2.0 licence and is a series of LF Projects, LLC, a Linux Foundation entity based in the United States. The project was originally created by EDB, a PostgreSQL company, and its website describes it as community-driven. Because it runs in the organisation's own Kubernetes clusters, the location of the data follows the chosen infrastructure, including clusters in the EU. For a European organisation this is an open, self-operated alternative to proprietary managed PostgreSQL services, with no vendor cloud in the data path. Governance rests with a US-based foundation.

Why digital sovereignty matters with CloudNativePG

CloudNativePG is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

CloudNativePG hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

CloudNativePG is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

What this means for your organisation depends on your whole stack and context. The free assessment weighs CloudNativePG together with your other vendors and gives a total score, a heatmap and the main risk drivers.
