AWS Serverless IT Automation

Serverless IT Automation

Implement a scheduled Lambda function to explore serverless automation.

A scheduled Lambda function will execute at a predefined time.

You may use CloudWatch Events to plan your Lambda function to run at a certain time.

This implies no server overhead for normal tasks.

You may use Step Functions and Lambda to create a collection of event-based actions.

For example, you may set an AWS Config rule that no security groups should enable public remote access.

When a security group is modified, a CloudWatch event is produced.

The CloudWatch event initiates a Lambda function with custom code that checks a list of security group rules.

It deletes the rule and uses Amazon SNS to send an email if the update fails.
