# Amazon ElastiCache 端點和配額
<a name="elasticache-service"></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。
