Cross-region inference in Amazon Bedrock AgentCore Memory, Amazon Bedrock AgentCore Policy, and AgentCore Evaluations

With cross-region inference, Amazon Bedrock AgentCore Memory, AgentCore Policy, and AgentCore Evaluations will automatically select the optimal region within your geography (as described in more detail below) to process your inference request, maximizing available compute resources and model availability, and providing the best customer experience.

For AgentCore Memory, AgentCore Policy, and AgentCore Evaluations, cross-region inference requests are kept within the AWS Regions that are part of the geography where the data originally resides. For example, a request made within the US is kept within the AWS Regions in the US. Although the data remains stored only in the primary region, when using cross-region inference, your input prompts and output results may move outside of your primary region. All data will be transmitted encrypted across Amazon's secure network.

Note

There's no additional cost for using cross-region inference.

Amazon CloudWatch and AWS CloudTrail logs won't specify the AWS Region in which data inference occurs.

For AgentCore Memory, if you don't want cross-region inference, you can manage your model selection using a built-in with overrides strategy.

For AgentCore Evaluations, if you don't want cross-region inference, please see additional information on creating custom evaluators that operate without CRIS.
