It sounds like you'd benefit from AWS Batch better for the scheduled tasks. After everything is up and running, all you need to do is submit a job (from a lambda function, CLI, whatever works best for you). Then, in cloudwatch event rules, you can setup a new rule that only triggers on failed jobs, which can then have a SNS/Lambda target. Or, alternatively, setup a cloudwatch alarm on the actual event rule invocations.
