Enable location restrictions on Compute Engine instances and virtual disk resources where the data is handled. Apply labels to tag geographic metadata for all stored data.

Use the Cloud Data Loss Prevention (Cloud DLP) API to scan for sensitive location data before any storage or processing. Create Cloud Storage buckets with global availability for optimal performance, relying on Cloud DLP results to filter and control data access.

Create regional Cloud Storage buckets with Object Lifecycle Management policies that limit data lifetime. Enable fine-grained access controls by using IAM conditions. Encrypt data with customer-managed encryption keys (CMEK) generated within specific Cloud KMS key locations.
