Vespa is an open-source engine for search, recommendation and AI applications. It combines text and vector search, ranking with machine-learned models and real-time data updates in one serving platform. Organisations can run the open-source software themselves under the Apache-2.0 licence published on GitHub, or use the hosted Vespa Cloud service, which the vendor says is also available on AWS.
Vespa.ai AS is registered in Trondheim, Norway, which is part of the European Economic Area. Its privacy policy names Vespa.ai AS as data controller and refers to the GDPR and the Norwegian Personal Data Act. It also notes that some service providers and analytics data may be processed outside the EU/EEA under standard contractual clauses. The vendor's pages do not list the hosting regions of Vespa Cloud. Self-hosting the open-source engine keeps data under the organisation's own control, while the cloud service's data locations should be confirmed before use.
