Azure Stream Analytics enable us to analyze data in real time. Connecting multiple streams of data, running queries on top of them without having to deploy complex infrastructure become possible using Azure Stream Analytics.
This Azure service is extremely powerful when you have data in the cloud. But there was no way to analyze the data stream at device or gateway level.
For example if you are in a medical laboratory you might have 8 or 12 analyzers. To be able to analyze the counters of all this devices to detect a malfunction you would need to push counters value to Azure, even if you don't need for other use cases.
Wait! There is a new service in town that enable us to run the same Azure Stream Analytics queries but at gateway or device level - Azure Stream Analytics on Edge Devices. Even if the name is long and has Azure in the name, the service is a stand alone service that runs on-premises.
This service allows us to run the same queries in real time over data streams that we have on our on-premises devices. From the job (query) perspective we have the same features like SQL language, temporal filters, window query and full integration with JavaScript code.
On of the key features of Azure Stream Analytics on Edge Devices is the low latency, that is perfect for systems where we need to react fast without downtime. This service comes as a component inside Azure IoT Gateway SDK, but doesn't limit us to use Azure, we can push data from our queries to our own custom modules.
Using this service we can now analyze data streams directly on our gateways and push to the cloud only the tings that we want. The same query that we have on the cloud we can run it now on our gateway and push only relevant data to Azure. Beside this, we can generate alerts or actions on our gateway from Azure Stream Analytics on Edge Devices and react directly on our gateway or device.
