Why choose Impossible Cloud over Amazon S3?

The decisive argument is data jurisdiction. Amazon S3 is headquartered in US, which means personal data processed through it can be subject to non-EU legal regimes — the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.

Impossible Cloud removes that overhead. As a Germany-based provider, it operates natively under GDPR, and data stays inside the EU/EEA by default. For regulated sectors — health, public administration, finance — that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single non-EU jurisdiction that can change the rules without warning.

Frequently asked questions

Is Impossible Cloud a good alternative to Amazon S3?
Yes — Impossible Cloud is one of the top-ranked European alternatives to Amazon S3 in our directory, covering the same cloud & hosting use case. It is headquartered in Germany, keeping your data under EU law by default.
What's the main difference between Impossible Cloud and Amazon S3?
The biggest difference is jurisdiction: Impossible Cloud is based in Germany and operates under GDPR and EU data-protection law, while Amazon S3 is headquartered in US and may transfer data outside the EU. For regulated industries or organisations following Schrems II guidance, this difference is decisive.
Is Impossible Cloud GDPR-compliant?
Impossible Cloud is a European company based in Germany, so GDPR compliance is the default operating model — not a bolt-on. No transfer impact assessment is required for EU customers, unlike when using Amazon S3.
How do I migrate from Amazon S3 to Impossible Cloud?
Start by exporting your data from Amazon S3 (most providers offer an export in their settings). Then import into Impossible Cloud using its native import tool or migration guide. Running both in parallel for a week catches any feature or workflow gaps before you fully switch.
