What functionality does AWS Config provide?

AWS Config is a powerful service that focuses on the continuous monitoring and recording of configuration changes to your AWS resources. It provides essential functionality that allows you to assess, audit, and evaluate the configurations of your cloud resources at any given time. By tracking changes to the configurations, AWS Config enables users to maintain compliance with internal policies and regulatory standards, and it allows for easier troubleshooting and operational oversight.

The service offers detailed information about the current configurations of your resources, a history of those configurations, and relationships between resources. This insight is invaluable for organizations that require comprehensive visibility into how their resources are changing over time, helping to ensure governance and quality control within the cloud environment.

The other options do not align with the primary objectives of AWS Config. Automating resource deployments refers more to services like AWS CloudFormation or AWS OpsWorks, managing billing and support cases pertains to services like AWS Budgets or AWS Support, and creating simplified user interfaces is more about management tools and dashboards rather than configuration monitoring. Thus, monitoring changes in AWS resource configurations is the core functionality of AWS Config.
