be required to accommodate the evolving needs of the SCHub, including positions for data
governance, system maintenance and cross-departmental coordination. Governance of the SCHub
itself must be well defined, including decision-making processes, stakeholder engagement, and
the establishment of protocols for ongoing management and adaptation to emerging technologies
and challenges.

Telemetry gateway: The telemetry gateways are software of hardware endpoints where the IoT
devices connect to transmit their information in a secure way. The telemetry gateway can be either
one-directional to service IoT devices that support only sending of information or bi-directional to
service IoT devices that support remote management and over-the-air firmware upgrade.

Figure 8: System Overview

Message Oriented Middleware: The Message Oriented Middleware (MoM) connects the
telemetry gateways and the Business Microservices. The MoM allows the scaling of the architecture
to accommodate a few IoT devices and gateways for a small pilot project to a full-blown deployment
with multiple gateways and hundreds of thousands of IoT devices and business services that
consume that data. Depending on the scale of the SCHub this component will be sized accordingly
to provide the required throughput at the proper cost for the SC.
