AWS Lambda now supports 90-minute function timeouts on Managed Instances
AWS Lambda has increased its function timeout for asynchronous and event source mapping (ESM) invocations on Lambda Managed Instances (LMI) to 90 minutes, a six-fold increase from the previous 15-minute limit. This enhancement allows developers to execute longer-running data processing, media transcoding, financial calculations, AI inference, and batch workloads without re-architecting applications. The extended timeout applies to asynchronous and ESM invocations, including those within Lambda durable functions, while synchronous invocations retain the 15-minute maximum. This capability is available in all AWS Regions where LMI is offered.

- Increased Lambda function timeout to 90 minutes for asynchronous workloads
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 customers to run data processing, media transcoding, financial calculations, AI inference, and batch workloads on Lambda that require longer continuous execution, reducing the need for architectural workarounds. The increased timeout also applies to invocations within Lambda durable functions, enabling multi-step executions for up to one year when invoked asynchronously.
