Azure Monitoring & Cloud Observability Hub 📊📈

Azure Monitor is Microsoft’s full-stack enterprise observability platform. It collects, correlates, and analyzes telemetry across three core operational pillars: Metrics (real-time numeric data for autoscaling), Logs (high-volume diagnostic data analyzed via Kusto Query Language), and Distributed Traces (Application Insights APM and OpenTelemetry), culminating in cloud-native SIEM/SOAR via Microsoft Sentinel.
