“Remote access to IoT devices: Common needs and approaches” by Eystein Stenberg

When deploying IoT devices to the field, they become inherently difficult to access physically. In the ideal case the devices always work predictably and you have an approach to do OTA software updates in a controlled manner, so you can systematically improve your device fleet over time, by fixing bugs, security issues and adding new features. In the real world, even if you do your due diligence and planning, strange things will happen to individual devices in the field. Your customers will contact you and ask why the product is not working according to their expectations. Is there something wrong with the device, software applications or the expectations/usage of the customer? This needs to be addressed right away, your customer is waiting. But where to start? Remote access is a common term used for different features, for example remote terminal, that will enable efficiently diagnosing such issues remotely. Based on research on solutions used across many different IoT product companies, we will go through
