AWS Lambda now supports 90-minute function timeout on Lambda Managed Instances

AWS Lambda 90-Minute Function Timeout

AWS Lambda now supports a 90-minute function timeout for asynchronous and event source mapping (ESM) invocations on Lambda Managed Instances (LMI), a 6x increase from the previous 15-minute limit. This allows for longer continuous execution for data processing, media transcoding, financial calculations, AI inference, and batch workloads without re-architecting applications.

Lambda Managed Instances enable processing multiple concurrent requests per instance, access to specialized compute configurations, and cost efficiency through EC2 pricing advantages, without managing infrastructure. The increased timeout also applies to invocations within Lambda durable functions, which allow for checkpointing and replaying steps for longer-running invocations.

What to do

• Configure up to a 90-minute function timeout for asynchronous and ESM invocations via the AWS Lambda Console, AWS CLI, Lambda APIs, Infrastructure as Code tooling, or the Agent Toolkit for AWS.
• Synchronous invocations retain the existing 15-minute maximum timeout.
• This feature is available in all AWS Regions where Lambda Managed Instances is available.
