Data residency and regional hosting for AI systems

Where prompts, embeddings, logs and backups live can matter as much as where the model runs. Map it before a regulator asks.

For many European and Indian clients, data location is a procurement requirement. AI systems spread data across more places than a conventional application.

Map every location

  • Prompts and responses in transit and at the provider.
  • Embeddings and vector stores.
  • Logs, traces and analytics tools.
  • Backups and caches.
  • Sub-processors and support access.

Then decide

  • Which data must stay in region, and which may leave under agreed conditions.
  • Which model endpoints are available in the required region.
  • How the region constraint is enforced and evidenced.

Get the data-flow diagram approved early. Retrofitting regional hosting is far harder than designing for it.
