D. Azure Files
E. Azure Table Storage

Answer

B. Azure Cosmos DB

Explanation

Azure Cosmos DB is a globally distributed NoSQL database, optimized for IoT workloads and real-time applications.

The best Azure service for handling IoT workloads with high-volume, time-series data is Azure Cosmos DB.

  • Purpose-Built for IoT and Time-Series: Azure Cosmos DB is a globally distributed NoSQL database service designed to ingest, store, and process massive amounts of data from IoT devices, including time-series telemetry such as sensor readings, logs, and events.
  • High Throughput and Low Latency: Cosmos DB is optimized for high ingestion rates and low-latency queries, making it ideal for real-time IoT analytics and dashboards.
  • Flexible Data Model: It supports various APIs (including SQL, Cassandra, MongoDB, Gremlin, and Table), allowing you to choose the best model for your IoT scenario and easily handle diverse device data structures.
  • Global Distribution and Scalability: Cosmos DB can replicate data across multiple Azure regions, ensuring high availability, disaster recovery, and low-latency access for global IoT solutions.
  • Optimized for Time-Series Storage: Cosmos DB can efficiently store and query time-series data, such as telemetry from thousands or millions of IoT devices, and is commonly used as the primary data store for IoT solutions in Azure.
  • Integration with IoT Services: It integrates seamlessly with Azure IoT Hub, Azure Stream Analytics, and other Azure services for end-to-end IoT solutions, including device management, anomaly detection, and predictive maintenance.

Supporting Evidence:

  • Microsoft documentation and industry case studies highlight Cosmos DB as the recommended service for storing IoT telemetry and time-series data due to its scalability, performance, and integration capabilities.
  • Real-world solutions use Cosmos DB to ingest, process, and analyze time-series data from distributed IoT devices for monitoring, analytics, and remote management.

Azure Cosmos DB is a globally distributed NoSQL database optimized for IoT and time-series workloads, providing the scalability, performance, and flexibility needed to store and analyze high-volume, real-time device telemetry data.
