 To explore serverless technologies in Azure, start with a serverless reference solution developed and tested by Microsoft. This two-part solution describes a hypothetical drone delivery system. Drones send in-flight status to the cloud, which stores these messages for later use. A web application allows users to retrieve these messages to get the latest status of these devices.
