Architectural difference: Event Hub = high-throughput ingestion, streaming, pub-sub; retention by time. Service Bus = messaging, queues, topics, dead-letter, sessions, transactions. Use Event Hub for: telemetry, IoT, clickstreams, data pipelines. Use Service Bus for: decoupling, workflows, ordered processing. Trade-off: Event Hub for scale; Service Bus for semantics. Best practice: Choose by pattern—streaming vs messaging.
Red Flag: Using Service Bus for high-volume telemetry. Pro-Move: 'Event Hub for 100K events/sec ingestion; Service Bus for order processing with FIFO—right tool per pattern.'
