AWS AppConfig is a service within AWS Systems Manager that enables us to manage and deploy application configurations quickly and safely. AppConfig allows us to make configuration changes to our applications without needing to deploy new code, which helps in maintaining high availability and reducing downtime.

AppConfig reduces errors in configuration changes by validating configuration data before deployment, ensuring early error detection, and preventing production issues. It provides a schema for validating configuration data, minimizing the risk of introducing incorrect settings.
