The benefits of a broader scope with a long-term view can be illustrated when discussing the use of Virtual Private Cloud. This particular choice eliminates the need to create new servers each time the organisation grows, as it can store compute analytics modules and other microservices to the cloud.
Another consideration that may be dismissed in a PoC is the potential for the payload size to increase. Different data types can have significantly different payload sizes and bandwidth requirements. Something as simple as a water level sensor for example, only collects and transmits small amounts of data at a time. Contrasted with a device that has the ability to capture satellite images, the payload requirements are significantly higher.
Organisations need to take into consideration emerging IoT capabilities when they design their overall IoT architecture, to ensure that it is prepared to take on future challenges as the scope expands.
