After the data has been ingested within the Cloud Gateway, the Steam Processing engine receives that telemetry and routes it to different down stream systems. This routing of telemetry messages can happen based on the type of message; for example, a particular type of message can be routed to a designated downstream system which processes only that particular type of message. This routing is very helpful in the case of segregating types of messages or taking priority action on a high priority message.

Azure Stream Analytics is one such Steam Processing engine available within Microsoft Azure, which allows the processing of data streams, such as aggregation of data, and then routing this stream of data to different permanent storage options such as Azure Blob, Azure Tables, Azure SQL Database, Azure Data Lake, and other data stores.
