Considering the specific requirement of providing a centralized service for collecting, analyzing, visualizing, and acting on monitoring data across applications, infrastructure, and network components, Azure Monitor is the most appropriate and purpose-built solution. It delivers a unified platform for observability, combining metrics, logs, traces, and alerts in one place, while also providing integration with automation and incident management systems. The other services play important roles in their respective domains—Blob Storage for scalable data storage, Synapse Analytics for enterprise-wide analytics, and SQL Managed Instance for relational database workloads—but none of them offer the extensive set of monitoring-focused functionalities required to serve as a centralized observability service. Azure Monitor stands apart because it addresses real-time visibility, centralized intelligence, operational health assessment, telemetry-driven automation, and complete observability across hybrid and cloud-native environments.
