Microsoft Certified: Azure Solutions Architect ExpertDesign infrastructure solutionsEasy
A global manufacturing company is designing a new IoT solution to monitor factory equipment across multiple geographically dispersed sites. The solution needs to ingest millions of data points per second, process them in near real-time for anomaly detection, and store them for long-term analytics. Which Azure service is most appropriate for ingesting this high-volume, high-velocity data stream?
- AAzure IoT Hub
- BAzure Queue Storage
- CAzure Service Bus
- DAzure Event Grid
Show answer & explanationAnswer & explanation
Correct answer: A. Azure IoT Hub
Azure IoT Hub is specifically designed for bidirectional communication between IoT devices and the cloud, making it ideal for ingesting high volumes of telemetry data from millions of devices, managing devices, and securely connecting them.
Why the other options are wrong
- B. Azure Queue Storage is a simple queueing service for message storage, not designed for real-time, high-throughput IoT data streams.
- C. Azure Service Bus is a messaging service for enterprise applications, not optimized for high-volume IoT telemetry.
- D. Azure Event Grid is an event routing service for reactive programming, not a primary data ingestion pipeline for IoT.
Azure IoT Hub
A cloud-hosted solution back end to connect virtually any IoT device to Azure. It provides secure, bidirectional communication between IoT devices and the cloud.
- Connects millions of IoT devices
- Ingests high-volume telemetry data
- Supports device management and security
Memory trick: IoT Hub collects all the tiny device whispers to tell the big cloud stories.
