# 支援跨區域防護機制推論的區域
<a name="guardrails-cross-region-support"></a>

使用 Amazon Bedrock Guardrails 進行跨區域推論，可讓您針對護欄政策評估使用不同 AWS 區域 的運算，無縫管理意外流量暴增。

[建立](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)防護機制時，您要指定支援一組來源和目的地區域的防護機制設定檔：
+ **來源區域** – 您提出防護機制推論請求所在的區域。
+ **目的地區域** – Amazon Bedrock 服務可路由防護機制推論請求的區域。

您可以使用的防護機制設定檔取決於防護機制所在的來源區域。
