Node 18 and Node 16 deprecation in AWS Lambda - time is up
If your business is running AWS Lambda functions built on Node.js 18 or Node.js 16, this is your final call. On 1 November 2025 - in a matter of days - AWS will flip the switch. From that point, you will no longer be able to update, redeploy, or modify any Lambda functions that still depend on those runtimes. They'll continue to execute for now, but essentially frozen in amber - unsupported, unpatched, and slowly drifting away from compliance.
