AWS Lambda 现支持在 Lambda Managed Instances 上的函数进行...

发布于: 2026年5月12日

AWS Lambda 现在支持通过 Amazon EventBridge 调度器对运行在 Lambda Managed Instances 上的函数进行计划的扩缩。此功能支持您定义一次性或周期性计划,在预期流量到来之前主动调整函数的容量限制,从而在高峰期满足性能目标,并在空闲期节省成本。

使用 Lambda Managed Instances,您可以在具有内置路由、负载均衡和自动扩缩功能的托管 Amazon EC2 实例上运行 Lambda 函数。容量会根据流量在您配置的执行环境最小值和最大值之间进行扩缩。此前,流量模式(例如营业时间应用程序或营销活动)可预测的客户必须在已知需求变化之前手动调整容量限制,或构建自定义自动化方案来按计划管理扩缩。借助计划扩缩功能,您现在可以定义计划,在预期流量到来之前主动调整函数的容量限制。例如,您可以安排在营业时间开始前提高容量限制,以便在收到第一个请求时执行环境已准备就绪。您还可以定义一个计划,在空闲期将容量缩减至零(这样您只需在函数实际处理流量时付费),并安排在流量恢复前重新扩展容量。

针对 Lambda Managed Instances 上运行的函数的计划扩缩功能现已在支持 Lambda Managed Instances 的所有 AWS 区域中提供。您可以通过 Amazon EventBridge 调度器控制台、AWS CLI、AWS SDK、AWS CDK 或 AWS CloudFormation 创建计划。如需了解更多信息,请访问 AWS Lambda Managed Instances 文档Amazon EventBridge 调度器文档AWS Lambda 定价以及 Amazon EventBridge 定价
