Improve resilience with cross-region inference

When running model inference in on-demand mode, your requests might be restricted by service quotas or during peak usage times. Cross-region inference enables you to seamlessly manage unplanned traffic bursts by utilizing compute across different AWS Regions. With cross-region inference, you can distribute traffic across multiple AWS Regions, enabling higher throughput and enhanced resilience during periods of peak demands.

To use cross-region inference, you include an inference profile when running model inference in the following ways:

To see the Regions and models with which you can use inference profiles to run cross-region inference, refer to Supported Regions and models for inference profiles.

To learn how to use an inference profile to send model invocation requests across Regions, see Use an inference profile in model invocation.

You can also increase throughput for a model by purchasing Provisioned Throughput. Inference profiles currently don't support Provisioned Throughput.

Note the following information about cross-region inference:

  • There's no additional routing cost for using cross-region inference. The price is calculated based on the region from which you call an inference profile. For information about pricing, see Amazon Bedrock pricing.

  • When using cross-region inference, your throughput can reach up to double the allocated quotas in the region that the inference profile is in. The increase in throughput only applies to invocation performed via inference profiles, the regular quota still applies if you opt for in-region model invocation request. For example, if you invoke the US Anthropic Claude 3 Sonnet inference profile in us-east-1, your throughput can reach up to 1,000 requests per minute and 2,000,000 tokens per minute. To see the default quotas for on-demand throughput, refer to the Runtime quotas section in Quotas for Amazon Bedrock or use the Service Quotas console.

  • Cross-region inference requests are kept within the regions that are part of the inference profile that was used. For example, a request made with an EU inference profile is kept within EU regions.

You can also increase throughput for a model by purchasing Provisioned Throughput. Inference profiles currently don't support Provisioned Throughput.
