# AWS Security Token Service 端點和配額
<a name="sts"></a>

若要以程式設計方式連線至 AWS 服務，您可以使用 endpoint. AWS services，在服務支援的部分或全部 AWS 區域中提供下列端點類型：IPv4 端點、雙堆疊端點和 FIPS 端點。有些 服務提供全域端點。如需詳細資訊，請參閱[AWS 服務端點](rande.md)。

服務配額也稱為限制，是 AWS 您的帳戶的服務資源或操作數量上限。如需詳細資訊，請參閱[AWS 服務配額](aws_service_limits.md)。

以下是此服務的服務端點和服務配額。

**注意**  
AWS 建議您在應用程式中使用區域 STS 端點，並避免使用全域 （舊版） STS 端點。區域 STS 端點可減少延遲、建置備援，並提高工作階段字符的有效性。如需設定應用程式以使用區域 STS 端點的詳細資訊，請參閱 *AWS SDKs和工具參考指南*中的[AWS STS 區域化端點](https://docs.aws.amazon.com/sdkref/latest/guide/feature-sts-regionalized-endpoints.html)。如需全域 （舊版） AWS STS 端點的詳細資訊，包括如何監控此端點的使用，請參閱*AWS 安全部落格*中的[如何使用區域 AWS STS 端點](https://docs.aws.amazon.com/sdkref/latest/guide/feature-sts-regionalized-endpoints.html)。

## 服務端點
<a name="sts_region"></a>

雖然全域 （舊版） AWS STS 端點`https://sts.amazonaws.com`高度可用，但它託管在單一 AWS 區域、美國東部 （維吉尼亞北部） 和其他端點，但它不提供自動容錯移轉到其他區域中的端點。根據預設，大多數區域端點皆為作用中，但是您必須手動啟用某些區域的端點，例如亞太區域 (香港)。對於預設為啟用的任何區域，如果您不打算使用這些區域，則可以停用其 STS 端點。
