Microsoft Azure Data FundamentalsDescribe an analytics workload on AzureMedium
A startup is building a new IoT solution that collects sensor data from thousands of devices every second. They need to analyze this data in real time to detect anomalies and trigger alerts instantly. Which Azure service is specifically designed for real-time stream processing and analytics?
- AAzure Data Factory
- BAzure Synapse Analytics dedicated SQL pool
- CAzure Data Lake Storage Gen2
- DAzure Stream Analytics
Show answer & explanationAnswer & explanation
Correct answer: D. Azure Stream Analytics
Azure Stream Analytics is a real-time analytics service that processes high volumes of streaming data from various sources to detect patterns and relationships, making it ideal for anomaly detection and instant alerting on IoT data.
Why the other options are wrong
- A. Azure Data Factory is for orchestrating batch ETL/ELT pipelines, not real-time stream processing.
- B. Dedicated SQL pool is for batch processing and warehousing structured data, not real-time stream analysis.
- C. Azure Data Lake Storage Gen2 is for storing large volumes of data, not real-time processing.
