Which AWS feature allows tracking changes made to resources over time?

AWS Config is the feature designed specifically to track the configuration changes made to AWS resources over time. It provides users with a detailed view of the configuration history, allowing for the assessment, auditing, and compliance of resources. AWS Config continuously monitors and records your AWS resource configurations and can alert you to any changes that may violate your policies, enabling you to maintain a consistent security posture and comply with regulatory requirements.

By maintaining a record of changes, AWS Config helps organizations understand how their AWS resource configurations evolve, which is crucial for troubleshooting, operational audits, and maintaining compliance with corporate policies or regulations.
