Exam AWS-SysOps topic 1 question 932 discussion

AWS Config allows you to create custom rules (AWS Config rules) to check the configuration of your AWS resources, including EC2 instances, against a set of desired configurations. By creating a custom AWS Config rule, you can track EC2 instances that do not have the required cost-related tags. When an EC2 instance is launched or modified and lacks the required tags, AWS Config can automatically detect this non-compliance and generate an evaluation result. This solution requires minimal operational overhead once the AWS Config rule is set up and enabled. AWS Config takes care of continuously monitoring the resources for compliance and automatically evaluates whether the required tags are present on EC2 instances, without the need for manual intervention.
