This article describes how Thomson Reuters built a scalable solution to monitor and track AWS Health alerts across thousands of AWS accounts using AWS services, ServiceNow, and Datadog.

• CloudWatch Scheduler invokes Lambda every 10 minutes to fetch AWS Health API data
• EventBridge routes AWS Health events to appropriate targets based on event type
• Scheduled changes and issues routed to ServiceNow for incident/change management
• Account notifications routed to Datadog for monitoring by Global Command Center
• DynamoDB stores AWS Health event history for minimum 2-year retention requirement
• Resource tags identify affected applications and owners for targeted notifications
• ServiceNow dashboards provide leadership visibility into AWS environment health
• Solution handles approximately 16,000 AWS Health events annually at scale

Thomson Reuters now efficiently tracks AWS Health events, automates notifications, and takes proactive measures to minimize application impact across their cloud environment.
