description AWS CloudWatch Alarms Overview
CloudWatch Alarms are the fundamental monitoring component that detects when a service deviates from its normal operational parameters (e.g., CPU > 90% for 5 minutes). In a DR context, these alarms are the *triggers* that initiate the failover process, often feeding into EventBridge or Lambda. They provide the necessary real-time visibility to know *when* to initiate the recovery playbook.
