Mastering Azure Serverless Computing

IoT and Edge devices

IoT devices can be used to gather and process data from various sources and use directly in the field. One important use case can be using IoT to feed data into Stream Analytics, which can work with it. Stream Analytics can call Azure Functions when it needs to perform custom processing of the data using algorithms that are not included in the product.

Another use case could be using an Azure function running inside a container deployed on an Edge device to process data before transmitting it to the cloud, to filter out data that is not important (or not in scope) to reduce the number of calls and bandwidth usage. The same Azure function can then run in the cloud to check the data using the same code.
