This is an interesting service with at least one quick, clear use: running "cron jobs" on AWS Lambda, though there certainly are other options, this seems nice.
You can do that with the AWS Cloudwatch schedule trigger already. Finch seems to allow sub-minute intervals though, which is something that was always missing from Cloudwatch for me.
Great idea. I was thinking about writing something like this that could be deployed to Azure Functions that could replace their Azure Scheduler, which is pretty awful
