An interesting new way to use the AWS Lambda service, which is one of the most interestin cloud innovations in the last few years.
"Do you need to run an AWS Lambda function on a schedule, without an event to trigger the invocation? This session shows how to use an Amazon CloudWatch metric and CloudWatch alarms, Amazon SNS, and Lambda so that Lambda triggers itself every minute—no external services required! From here, other Lambda jobs can be scheduled in crontab-like format, giving minute-level resolution to your Lambda scheduled tasks. During the session, we build this functionality up from scratch with a Lambda function, CloudWatch metric and alarms, sample triggers, and tasks."
