Discussion on "How to Use cron Jobs to Schedule Your Lambda Functions with AWS CDK"

When building projects with AWS, there will come a time when you need to run things on a consistent and regular basis. A common example of this would be running a Lambda function once per day to perform some checks against a database. But, how do we ...

I have done it previously with the EventBridge Scheduler and am planning on writing a separate blog post on using the scheduler for some more advanced use cases.

However, for something like scheduling a Lambda to run once per day at the same time or a recurring timeframe, I felt EventBridge Rules was a better fit because it's simpler to implement and also there are some restraints on the Scheduler still I believe:

It's not fully implemented in the CDK so you'd need to use the SDK inside a Lambda function adding to the complexity
It's only available in a small subset of regions where Rules are available in every region I believe.

Saying this I am still planning on doing a Scheduler post in the future, so keep an eye out for that. 😃
