AWS Lambda and Azure Functions both support timer triggers and probably round down to $0/ month if your job only runs for a few seconds an hour

I exclusively use Lambda with Cloudwatch Rules for all the crons I write these days. It just works out of the box.

You should check out EventBridge Scheduler. Just released last month and seems like the go-to solution for such things going forward. I especially like the "run once at this time in the future" feature.

That’s neat! I remember hacking that together at an old job using step functions with a “pause until Timestamp” step.

Is that the same event source that's been available to the aws::serverless::function transform for awhile now?

Yep and with the CDK it's not only easy to spin up, it's super easy to connect services to it.

I wrote a notifier for when a local business has open appointments. A quick fetch every day and connected it to SNS seamlessly. Now I can easily add family members if they want the notifications and they can easily unsubscribe right from the email. All within the free tier.

Yeah, this is exactly where my mind went too. I think it’s a great example of not jumping to technical solutions too fast. The poster was so locked in on specifically cron as a solution that they forgot what they really want is code or jobs to run on a schedule and then missed alternate solutions.

You get something like a million lambda executions per month in the free tier.
