If you plan to deploy large-file packages, with file size larger than 100 MB, it is recommended to utilize byte range requests for a reliable download performance.
The Device Update for IoT Hub service utilizes Content Delivery Networks (CDNs) that work optimally with range requests of 1 MB in size. Range requests larger than 100 MB are not supported.
The following table shows the enforced throttles for operations that are available in all Device Update for IoT Hub tiers. Values refer to an individual Device Update instance.
