Azure Messaging & Event Architecture 📨⚡

Azure’s messaging and eventing portfolio decouples distributed microservices, facilitates high-throughput telemetry ingestion, and powers event-driven serverless workflows.

NOTE

This domain has been expanded into the comprehensive Azure Application Integration & Messaging Hub, which covers Enterprise Messaging (Service Bus), Streaming (Event Hubs), Reactive Event Routing (Event Grid), iPaaS Workflows (Logic Apps), and API Gateways (APIM).
