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.
