Azure Service Bus is designed for high-value enterprise messaging with commands and pub-sub, whereas Event Hubs is optimal for high-throughput telemetry and streaming data scenarios.

Configure dead-lettering and retries in Azure messaging by setting delivery guarantee policies on Service Bus or Storage Queues, routing failed messages to DLQs after exhausting retry limits.

Idempotency in Azure event-driven architectures is achieved by designing message consumers that safely handle duplicate deliveries, preventing side effects when retries occur across Service Bus or Event Grid.

Azure Event Grid is purpose-built for decoupled pub-sub workflows, enabling reactive event-driven architectures by routing events from Azure services to subscribers based on content filters.

Choose the optimal Azure messaging service by mapping your workload requirements to service capabilities: Storage Queues for simple async processing, Service Bus for commands, and Event Hubs for streaming.

Azure Service Bus supports message ordering through sessions and provides robust access control, allowing secure retention policies and scalable monitoring across decoupled messaging workflows.
