Table 8-2 :
You are a software architect . You are building a system or product line , and you control the architecture . You critically need to integrate components written by different programmers or even entire teams .
You are a device manufacturer , with the goal of making devices that will sell into many applications . The device offers services , such as configure , start , stop , etc . You have no idea how the device will eventually be used . Your users are likely not software experts ; they just want to add or integrate the device into a work cell .
You are building mobile apps or web browser based applications to provide the human machine interface . You need an easy way to support clean human interaction and access to backend services .
You are building a wide-area wireless system that needs to allow applications and devices to share data and information . The devices use various technology and domainspecific protocols . The applications and devices you integrate rely on leveraging the services provided by the communications provider network .
A data-centric approach will define the interfaces , capture the dataflow , enable module evolution , and enforce interoperation between teams . This approach also eases redundancy , fast complex data flow , and selective data filtering .
A device-centric approach will allow the device users to write generic software that will interoperate with competitor ’ s devices .
A RESTful approach will make it easy to connect to many types of enterprise systems and UI devices .
A common , standard services-layer approach enables applications and device to share data and information without forcing the application to understand multiple protocols implemented on the devices . The applications can thus run in the Platform Tier and seamlessly connect to diverse IoT devices in the field .

Non-overlapping system aspect examples addressed by the potential IIoT connectivity core standards .
Core gateways enable horizontal data interoperability between components across functional domains , as shown in Figure 3-4 . Other connectivity technologies can integrate into the system architecture using a gateway to one of the core connectivity standards . This satisfies the range of IIoT system architecture challenges with minimum complexity .
