# 支持跨区域护栏推理的区域
Cross-Region 借助 Amazon Bedrock Guardrails 进行推理，您可以通过使用不同的 AWS 区域 计算来进行护栏策略评估，从而无缝管理计划外的流量爆发。
[创建](https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-components.html)或[修改](https://docs.aws.amazon.com/bedrock/latest/userguide/guardrails-edit.html)护栏时，您需要指定支持一组源区域和目标区域的护栏配置文件：
+ **源区域** – 您提出护栏推理请求的区域。
+ **目标区域** – Amazon Bedrock 服务可以将护栏推理请求路由到的区域。
您可以使用的护栏配置文件取决于护栏所在的源区域。
## 可用的护栏配置文件
展开以下部分之一，查看有关护栏配置文件、可在其中使用该配置文件的源区域以及该配置文件可将请求路由到的目标区域的信息。
