With cross-region inference, Amazon Q Business 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. With cross-region inference, you get:
-
Complete access to most advanced Amazon Q Business AI capabilities and features
-
Access to a variety of models suitable for different tasks
-
Improved performance for all your applications
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.
