Which service can be integrated to analyze IoT data in real-time?

The option that allows for the real-time analysis of Internet of Things (IoT) data is Azure Stream Analytics. This service is designed specifically for processing and analyzing streaming data from various sources, including IoT devices. It allows users to set up real-time analytics queries that can process data as it arrives and provide insights or trigger actions almost instantaneously.

By using Azure Stream Analytics, organizations can gain immediate visibility into operations, detect patterns or anomalies in their IoT data streams, and derive actionable intelligence to improve decision-making. This capability is crucial in scenarios where timely responses are necessary, such as monitoring equipment performance, managing smart devices, or responding to alerts generated from IoT data.

In contrast, Azure Functions is a serverless compute service that can run code in response to events, but it does not specialize in real-time data analytics. Azure Blob Storage is primarily used for storing large amounts of unstructured data and is not designed for analytics. Azure Active Directory is an identity and access management service, which plays no role in data analysis or IoT integration.
