Impossible Cloud: sovereignty score and 8 European alternatives

Impossible Cloud is a European cloud infrastructure provider founded in 2021. Its core product is object storage that is fully compatible with the AWS S3 API, so existing S3 tools and workflows can work without changes. The company also offers bare-metal GPU servers and serverless inference for open-weight models. According to the company, the storage runs on a proprietary, vertically integrated stack with an always-hot storage model and erasure coding. The service is delivered through a web console and the S3 API and targets enterprises as well as partners, MSPs and resellers.

The company is headquartered in Hamburg, Germany, and is privately owned by its co-founders Kai Wawrzinek and Christian Kaul together with European venture capital firms and other investors. According to the provider, data is stored in ISO-certified data centres in Germany and other European regions, including a newly launched French region. The product is not open source. The website also refers to regions elsewhere in the world, so organisations that need EU data residency should fix the region when they create their storage.

Why digital sovereignty matters with Impossible Cloud

Impossible Cloud is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Impossible Cloud scores best on data residency.

Impossible Cloud 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 Impossible Cloud together with your other vendors and gives a total score, a heatmap and the main risk drivers.
