Azure Blob Storage: sovereignty score and 8 European alternatives

Azure Blob Storage is Microsoft's cloud object storage for unstructured data, such as application files, backups, archives and data used for analytics and machine learning. It is offered in tiers from Premium to Archive, and lifecycle management can move data between them. Developers can use it from Java, .NET, Python and Node.js. It is delivered as a cloud service within Microsoft Azure, and Azure Data Lake Storage builds on it.

Microsoft is a US company, so Azure Blob Storage can be subject to US law such as the CLOUD Act, whatever region is chosen. When creating storage, customers select a geography and region. Microsoft's regions page lists European regions in countries including Austria, Belgium, Denmark, Germany, France, Sweden and Switzerland, and states that each geography meets specific data residency and compliance requirements. The page does not confirm that data stays in the selected region. Microsoft's Data Protection Addendum, referenced in its licensing terms, governs the processing of customer data.

Why digital sovereignty matters with Azure Blob Storage

Azure Blob Storage 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.

Azure Blob Storage hosts data in EU, US. 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.

Azure Blob Storage 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 Azure Blob Storage together with your other vendors and gives a total score, a heatmap and the main risk drivers.
