Microsoft Azure Stream Analytics is a serverless scalable complex event processing engine by Microsoft that enables users to develop and run real-time analytics on multiple streams of data from sources such as devices, sensors, web sites, social media, and other applications.

[1] Users can set up alerts to detect anomalies, predict trends, trigger necessary workflows when certain conditions are observed, and make data available to other downstream applications and services for presentation, archiving, or further analysis.

[2] Users can author real-time analytics using a simple declarative SQL-like language with embedded support for temporal logic.

Callouts to custom code with JavaScript user defined functions extend the streaming logic written in SQL.

[3] Users can build real-time dashboards with Power BI for a live command and control view.
