AWS Spring clean is an automated way to clean your environment on daily basis to avoid unwanted spending. It uses multiple aws services to achive the same. CRUD operations performed on resources within your account and region are monitored through AWS Config, these events are captured and processed before sending relavent data to DynamoDB for persistent storage. Services would be checked for key-value pair Retain:True, if not present will be marked for termination. At 18:00 IST the Function is invoked to perform the scan of items present in the Table and send out the report to S3 bucket, with a notification to relavent stakehoder. Finally at 00:00 IST the Function is invoked to perform the delete operation on marked resources for termination. Save the report for the same in the S3 Bucket with notification to the respective stakeholder.
