AWS Config allows you to audit, evaluate, and assess the configurations of your AWS resources. Config monitors and records all configurations of your AWS resources and allows you automate the evaluation of these configurations against desired configurations. Config allows you to review changes in configurations, relationships between AWS resources, and dive into detailed resource configuration histories. You can also determine your overall compliance with the configurations defined in your internal guidelines. This allows you to simplify compliance auditing and change management as well as operational troubleshooting.
