How do I configure auto-scaling settings to scale down the instance count to zero when not actively processing requests?
如何設定自動擴展設定，以在未主動處理請求時將執行個體計數縮減規模為零？
You can scale down the SageMaker Asynchronous Inference endpoint instance count to zero in order to save on costs when you are not actively processing requests. You need to define a scaling policy that scales on the "ApproximateBacklogPerInstance" custom metric and set the "MinCapacity" value to zero. For step-by-step instructions, please visit the autoscale an asynchronous endpoint section of the developer guide.
您可以在未主動處理請求時將 SageMaker 非同步推論端點執行個體計數縮減規模至零，以節省成本。您需要定義依「ApproximateBacklogPerInstance」自訂指標擴展的擴展政策，並將「MinCapacity」值設定為零。如需逐步說明，請瀏覽開發人員指南的自動擴展非同步端點部分。
