This is one of the main strengths of AWS CDK where we can export our Lambda function as an object for other infrastructures to leverage on.

You can do the following: Export log data to S3 buckets that are encrypted by AWS Key Management Service (AWS KMS) Export log data to S3 buckets that have S3 Object Lock enabled with a retention period To begin the export process, you must create an S3 bucket to store the exported log data. Otherwise, there is no way we would know if our pipeline is working. 1 You can use boto3 in lambda and export logs into S3 need to write a lambda function thatcsubscribe to CloudWatch logs and triggered on cloud watch log events.

We want to send notifications from S3 to our Lambda whenever we put a file into our S3 bucket, and in this tutorial, we are using AWS CDK in Typescript to achieve that. Open the eventbridge console, create a rule for target as lambda function to run every 5 min to export the cloudwatch logs to s3 bucket.
