Exploration Summary

• Route 53

  • Latency-Based Routing: Inspect Route 53 records for latency-based routing policies for API Gateway endpoints.

  • Health Checks: Review health checks linked to CloudWatch alarms.

  • Canaries: Analyze canaries monitoring API Gateway endpoints and creating alarms for Route 53 health checks.

• API Gateway

  • Endpoints and Integration: Review regional API Gateway endpoints and their integration with backend services.

  • Caching and Throttling: Explore caching and throttling configurations.

  • Logs and Monitoring: Analyze API Gateway logs in CloudWatch

• DynamoDB Global Tables

  • Replication Settings: Check replication settings and ensure tables are properly configured across regions.

  • Replication Status: Review the health and synchronization status of global tables.

  • Query Data Consistency: Analyze data consistency settings (eventual or strong) across regions to meet application requirements.

  • Latency: Monitor replication latency between regions to ensure timely data synchronization.

  • Conflict Resolution: Inspect mechanisms for resolving simultaneous updates in different regions.

  • Monitoring: Review CloudWatch metrics such as replication errors, consumed capacity, and throttling rates.

• Aurora Global Database

  • Global Clusters: Inspect the global clusters. Review details about primary and secondary region configurations.

  • Replication Status: Check the replication status and lag between regions. View associated metrics in the cluster details.

  • Failover Readiness: Explore the failover settings and verify the designated failover region.

  • Reader Endpoints: Review regional reader endpoints for low-latency reads and ensure their availability.

  • Monitoring Metrics: Open CloudWatch from the console to monitor replication lag, write IOPS, and other performance metrics.

  • Data Consistency: View Aurora's real-time consistency features in the cluster properties.

  • Backups: Inspect automated backup and snapshot settings across regions.

• CloudWatch

  • API Gateway: Monitor key metrics (latency, error rates, request counts) and review logs for performance and troubleshooting insights.

  • Canaries: Inspect canary execution results, success rates, and logs to validate endpoint performance and uptime.

  • Alarms: Review alarms for API Gateway and canary metrics, ensuring thresholds, notifications, and automated actions are properly configured.
