How to Use Amazon Nova Sonic 2 Across Regions with AWS

Select Language:

If you want to access Amazon Bedrock Nova models, like Nova Sonic 2, from a region where they aren’t directly available, you can take advantage of Amazon Bedrock’s cross-region inference feature. This tool allows you to use foundation models across different AWS regions without compromising your security settings.

Here’s a simple guide on how to set this up, especially if region restrictions are in place:

First, you need to adjust your Service Control Policies (SCPs). Create an exception in your policies to permit specific Bedrock actions between regions. This can be done by adding permissions for actions like bedrock:InvokeModel* on particular resources in the necessary regions. This way, your broader regional restrictions stay intact, but you still gain access to the models you need.

If you’re using AWS Control Tower, you should modify its exemption parameters as well. Specifically, update the configuration to exempt certain Bedrock actions from region deny controls. Adjust the ExemptedActions setting to include bedrock:InvokeModel*. This change allows the models to be invoked across regions without triggering the usual restrictions.

To implement these changes effectively:

Turn off any region deny guardrails that may be too restrictive for your use case.
Enable more specific controls that allow exceptions only for the necessary Bedrock actions.
Set the configuration parameters to permit cross-region model invocation.
Test carefully to confirm that users can access Bedrock models in the desired regions but remain restricted from other services.

When setting this up, always follow best practices:

Use the principle of least privilege—only grant permissions that are necessary.
Monitor cross-region traffic to catch any potential issues early.
Regularly review and update your exemptions as Amazon Bedrock expands to more regions.
Keep detailed records of any exceptions made for auditing purposes.

Using cross-region inference offers a lot of benefits, including the ability to distribute workloads across multiple regions, which can increase processing speed and help handle unexpected traffic spikes more smoothly. This method helps ensure your models are accessible when and where you need them most, all while keeping your overall environment secure.
