Design and Manufacturing Layer - IoT Lens

Design and Manufacturing Layer

The design and manufacturing layer consists of product conceptualization, business and technical requirements gathering, prototyping, module and product layout and design, component sourcing, and manufacturing. Decisions made in each phase impact the next logical layers of the IoT workload described below. For example, some IoT device creators prefer to have a common firmware image burned and tested by the contract manufacturer. This decision will partly determine what steps are required during the Provisioning layer.

You may go a step further and burn a unique certificate and privacy key to each device during manufacturing. This decision can impact the Communications layer, since the type of credential can impact the subsequent selection of network protocols. If the credential never expires it can simplify the Communications and Provisioning layers at the possible expense of increased data loss risk due to compromise of the issuing Certificate Authority.
