Announcing 90-minute function timeout on AWS Lambda Managed Instances

AWS Lambda now supports 90-minute function timeouts on Managed Instances for asynchronous and event source mapping invocations, a 6x increase from the previous 15-minute limit.

• Enables data processing, media transcoding, AI inference, and financial calculation workloads without re-architecting applications
• Synchronous invocations retain the 15-minute maximum timeout
• Durable functions can run for up to 1 year when invoked asynchronously with 90-minute per-invocation limits
• Configure timeout via AWS CLI, CloudFormation, SAM, or Lambda console without code changes
• No additional charge; standard Lambda Managed Instances pricing applies
• Event source mappings require adjusted queue visibility timeouts and batching windows for SQS, Kinesis, and DynamoDB Streams
• Best practices include managing network idle timeouts, credential refresh, and implementing idempotency for longer-running functions

This enhancement allows customers to run longer-duration workloads on Lambda's serverless platform while maintaining simplicity and cost efficiency through EC2 pricing advantages.
