Unlocking AI flexibility in Europe: A guide to cross-region inference for EU data processing and model access

Summary

Amazon Bedrock's Cross-Region Inference (CRIS) is a managed capability designed to route generative AI model inference requests across multiple AWS Regions, addressing high demand for models and compute while meeting security and privacy requirements. CRIS uses inference profiles, which define the permissible Regions for request routing, optimizing for model throughput and low latency. System-defined profiles include Global inference, routing to any supported AWS commercial Region for maximum resilience and potential cost savings, and Geographic CRIS, such as EU CRIS, which restricts routing to AWS Regions within the European Union. Data transmitted via CRIS is encrypted and remains within the secure AWS network. AWS Identity and Access Management (IAM) controls access, and AWS CloudTrail logs API calls, including source and destination Regions, for auditability. Model Invocation Logging can capture full request/response payloads in the source Region.

Key takeaway

For AI Architects designing generative AI solutions in Europe, you should evaluate Amazon Bedrock's Cross-Region Inference (CRIS) to balance model availability, performance, and data residency requirements. Utilize EU CRIS profiles to ensure inference requests remain within EU AWS Regions, aligning with GDPR and local data processing obligations. Configure AWS IAM to control access to specific CRIS profiles and enable CloudTrail for auditability, providing transparency on data processing locations.

Key insights

Amazon Bedrock's CRIS enables flexible, compliant generative AI inference across AWS Regions, optimizing capacity and data residency.

Principles

• Data in transit via CRIS is encrypted within the AWS network.
• Inference profiles define geographic routing boundaries.
• Logging occurs in the source Region for compliance.

Method

CRIS routes inference requests by specifying an inference profile ID (e.g., "eu.amazon.nova-2-lite-v1:0") instead of a plain model ID in the API call.

In practice

• Use `list_inference_profiles` API to check available profiles.
• Configure IAM to enforce least privilege for CRIS profile access.
