The head end system (HES) and the application platform for IIoT provide different services to different domains. On one hand, the HES manages the communication network to allow continuous operations as well as manage all the devices and sensors accessing the IIoT network.
On the other hand, the application platform needs to guarantee essential functions such as communication security and data collection as well as provide a single-entry point for all the Big Data applications by means of high-level, standard based Application Programming Interfaces (APIs).
Just like the two previous elements, the HES must be designed with versatility in mind, since it needs to support both the communication infrastructure and the devices for their entire lifetime. Just as the IIoT communication infrastructure must be designed to expand from local to nationwide coverage, the HES must be highly scalable and based on a truly solid architecture.
