You can do the same with AWS...

- set a CloudWatch scheduled rule to schedule a lambda.

- or set a rule to send an sns, subscribe a queue to the sns topic and subscribe a lambda to the queue.

CloudWatch is cron based, which means you can't schedule a one time event.

Agree regarding sns, but in our case sns == s3

AWS adds a year parameter to cron. You can specify the exact time.

Why use S3? S3 events aren’t guaranteed. SNS was specifically designed for this use case.
