Google Cloud Firestore: sovereignty score and 8 European alternatives

Google Cloud Firestore is a serverless NoSQL document database for mobile, web and server applications. Data is stored in documents within collections, with nested objects, filterable queries, listeners that push changes to clients in real time, offline support, strong consistency and ACID transactions. The Enterprise edition offers a MongoDB-compatible API. Firestore is delivered only as a managed cloud service, with SDKs for Apple, Android, web, Node.js, Java, Python and Go, among others.

Firestore is a Google product, and Google is a US company. When creating a database you choose a regional or multi-region location. European options include the multi-region eur3 (Belgium and the Netherlands, with a witness replica in Finland) and regions such as Frankfurt, Paris, Milan and Warsaw; London and Zurich are also available. Google describes in its Cloud Data Processing Addendum that it acts as a processor under the GDPR. Because the provider is a US company, US law continues to apply even when data is stored in Europe. This matters for sensitive data and for decisions about encryption keys and data residency.

Why digital sovereignty matters with Google Cloud Firestore

Google Cloud Firestore 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.

Google Cloud Firestore hosts data in EU, CH, OTHER. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

Google Cloud Firestore is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

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