Does Sanity run on Google Cloud or AWS infrastructure?

Yes, that's correct! Sanity runs entirely on Google Cloud Platform infrastructure, not AWS. All Sanity services and customer data are hosted exclusively on GCP servers, so you're good to go with your customer's no-AWS policy.

Specifically, Sanity's primary data storage is located in Google Cloud Platform's data centers in St. Ghislain, Belgium (europe-west1 region). The platform uses Google Compute Engine servers, Google Container Engine clusters, and Google Cloud Storage for data persistence.

For content delivery, Sanity leverages Google's global CDN network to serve assets and API responses through points of presence worldwide, but the core infrastructure and data storage remains on GCP.

This single-provider approach on Google Cloud also means Sanity benefits from GCP's extensive security certifications including ISO 27001, SOC 2, HIPAA, and PCI DSS compliance. You can find more details about Sanity's infrastructure and security practices on their security page.

If your customer needs formal documentation for compliance purposes, you can also check Sanity's subprocessor list and Data Processing Agreement (DPA), which should confirm Google Cloud Platform as the infrastructure provider.
