Azure Functions: sovereignty score and 8 European alternatives

Azure Functions is the serverless compute service of Microsoft Azure that runs code in response to events without the customer managing servers. Triggers start a function and bindings connect functions to resources such as Azure Blob Storage or Azure Cosmos DB. Supported languages include C#, Java, JavaScript, PowerShell and Python. Hosting plans include Flex Consumption, Premium, App Service and Azure Container Apps, and Durable Functions supports long-running, stateful workflows.

Azure Functions is part of Microsoft Corporation, a publicly traded US company headquartered in Redmond, Washington, with no named majority shareholder. The service runs in Azure regions, including locations in Germany, France, Sweden, Italy, Poland and Spain, and the customer selects the region. Microsoft publishes a Data Protection Addendum for its online services. For a European organisation, the relevant points remain the US headquarters, the reach of US law, and the customer's own choice and verification of an EU region.

Why digital sovereignty matters with Azure Functions

Azure Functions 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 Functions hosts data in US, EU, 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.

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