Enable Amazon Bedrock cross-Region inference in multi-account environments
Machine Learning Blog
This article discusses how to enable Amazon Bedrock cross-Region inference in multi-account environments while maintaining strict Regional access controls. Key insights include:
- Cross-Region inference allows seamless traffic routing across different AWS Regions
- Service Control Policies (SCPs) can inadvertently block cross-Region inference functionality
- Organizations can modify existing SCPs to allow Amazon Bedrock cross-Region inference
- Two primary approaches are outlined for AWS Control Tower environments:
- Extending Region deny SCPs
- Enabling denied Regions with conditional blocking
The goal is to maintain compliance and security while enabling flexible AI model access across multiple Regions. No additional cost is associated with cross-Region inference.
