Now evaluate AWS Config Rules on demand, trigger rules on both configuration changes and periodic frequency, delete evaluation results, and assess a broad set of resources

With AWS Config Rules, you can define guidelines for provisioning and configuring AWS resources and then continuously monitor compliance with those guidelines.
