How To Trigger a Lambda Function on a Timer - Step by Step Tutorial

Recurring tasks on a timer are a common need for many software applications. Combined with a Lambda function and Eventbridge, AWS allows us to invoke a Lambda function on a periodic timer or interval. In this step by step video, I show you how to link your Lambda function and a Eventbridge Rule.

Thank you for the video, it is very brief and well explained. I just wanted to point out that the cron configuration for every minute is wrong, as it is in the video it wil execute your function at minute 1 every hour. The correct cron expression would be: (* * * * ? *)

Just implemented via cdk this kind of lambda invocation yesterday to automatically stop my ec2 in the evening because sometimes i forget to do it manually. Nevertheless great video!

The cron expression cron(1 * * * ? *) indicates running the task at the 1st minute of every hour, not every minute.

So, it will run once per hour, specifically at the 1st minute of each hour. Therefore, it will run 24 times a day, once per hour.

Thanks for this video. However, I have a question. My lambda function gets data from some API and processes the requests. When I try to run this function every minute using cloudwatch event triggers, the lambda function runs initially and then doesn't run every minute. Could you please explain why this is the case and provide a possible solution?
Thank you.
