A centralized monitoring system provides: Unified Visibility: Single pane of glass for all services, applications, and infrastructure Proactive Alerting: Detect and respond to issues before they impact users Performance Optimization: Identify bottlenecks and optimization opportunities Cost Management: Track resource utilization and spending patterns Compliance: Meet audit and regulatory requirements for logging Troubleshooting: Quickly diagnose and resolve production issues This comprehensive guide demonstrates how to build a production-ready centralized monitoring system using AWS CloudWatch and Grafana, deployed with CDK (TypeScript).
