AWS Lambda supports scheduled scaling for functions on Lambda Managed Instances

AI Impact Summary

AWS Lambda now supports scheduled scaling for functions running on Lambda Managed Instances, using Amazon EventBridge Scheduler. This capability allows you to define one-time or recurring schedules that proactively adjust your function's capacity limits ahead of expected traffic, to meet your performance targets during peak periods and avoid costs during idle periods. Lambda Managed Instances lets you run Lambda functions on managed Amazon EC2 instances with built-in routing, load balancing, and autoscaling. Capacity scales between your configured minimum and maximum execution environment limits based on traffic. Previously, customers with predictable traffic patterns, such as business-hours applications or marketing events, were required to manually adjust capacity limits ahead of known demand changes or build custom automation to manage scaling on a schedule. With scheduled scaling, you can now define schedules that proactively adjust your function’s capacity limits ahead of expected traffic. For example, you can schedule capacity limits to increase before business hours so execution environments are ready when the first requests arrive. You can also define a schedule that scales capacity to zero during idle periods (so you only pay when the function is actively serving traffic), and schedule it to scale back up before traffic returns. Scheduled scaling for functions running on Lambda Managed Instances is available in all AWS Regions where Lambda Managed Instances is supported. You can create schedules using the Amazon EventBridge Scheduler console, AWS CLI, AWS SDK, AWS CDK, or AWS CloudFormation.
