Frequently Asked Questions
Common questions about AWS Lambda releases and lifecycle.
How does AWS Lambda runtime deprecation work?
AWS announces runtime deprecation about 60 days before Phase 1, when you can no longer create new functions. Phase 2 follows, blocking updates to existing functions. Phase 3 eventually blocks invocations. Always migrate before Phase 1 hits.
Which Lambda runtimes are currently supported?
Check the version table above for current status. AWS supports runtimes for Node.js, Python, Java, .NET, Ruby, and Go. Custom runtimes via Amazon Linux have their own lifecycle.
How do I know when my Lambda runtime is being deprecated?
AWS sends email notifications and posts to the AWS Lambda blog. You can also check the Health Dashboard and this tracker for early warnings.
What happens if I do not upgrade a deprecated Lambda runtime?
After Phase 2 deprecation, you cannot update function code or configuration. After Phase 3, invocations will fail. AWS does not auto-migrate your functions to newer runtimes.
