how to trigger it like cron job?

[yunw]

what other aws services can be integrated here to enable the automatic execution instead of manually giving the payload? In my case, I had enabled cross region replication for S3 new objects update. this tool is very useful to do a weekly or daily period checking for orphan objects or old objects which are CRR enabled earlier. how i can launch it in a weekly base or daily basis? I had tried CloudWatch Event, even though supporting steps as target, but not necessary for this use case.

Thanks

Hi yunw,

thank you for your question.

Yes, you can trigger a lambda function or a step functions state machine execution at scheduled timings/intervals similarly to cron by using CloudWatch Events Scheduled Events. This is the recommended approach for your use case.

See the CloudWatch Events documentation here: https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/WhatIsCloudWatchEvents.html

What exactly have you tried when using CloudWatch Events before and what issues did you encounter leading you to think this may not work for your use case?

Thanks,
Constantin
