A logistics company must process millions of IoT sensor events in real time. Which Azure service is designed for that scenario?

Azure Event Grid is a highly scalable, fully managed event routing service that enables real-time processing of millions of events. It's ideal for IoT scenarios where sensor data needs immediate ingestion and processing, allowing for event-driven architectures. Azure Logic Apps is a serverless workflow service, good for orchestrating tasks but not primarily for high-volume event ingestion. Azure Virtual Network provides network isolation and connectivity, not event processing. Azure Blob Storage is for storing large amounts of unstructured data, not for real-time event processing.
