Which feature provided by AWS enables Automated Remediation?

Automated Remediation in AWS is primarily facilitated through AWS Lambda, which allows users to run code in response to events such as system changes or alerts. Specifically, AWS Lambda can be invoked automatically by various AWS services to perform tasks that address issues detected in the infrastructure, without manual intervention.

For instance, when monitoring tools identify anomalies or errors in your environment, they can trigger a Lambda function that executes predefined code to resolve the issue – whether that involves scaling resources, changing configurations, or even creating new instances. This automation helps improve the reliability and availability of applications by enabling quick responses to problems.

Other options, while they have their respective functionalities, do not specifically focus on automated remediation at the same level as Lambda does. Event Center pertains to aggregating and visualizing operational data rather than executing remediation actions. SNS (Simple Notification Service) is useful for alerting stakeholders about events, but it does not directly perform corrective actions on its own. Express Route doesn’t pertain to AWS services but rather relates to Azure networking, which is not relevant in the context of AWS features for automated remediation. Thus, the use of AWS Lambda stands out as the primary enabler of automated remediation in AWS environments.
