Summary
Software design and development is a well-defined process that starts with requirement analysis and software design. In this chapter, we explored the software design for an automotive IoT application, focusing on remote diagnostics. We introduced the cloud backend deployment (public, private, and hybrid clouds) and service models (IaaS, PaaS, and SaaS). The IoT application architecture was examined through components such as cloud device gateways, edge computing, stream processing, and device management. OTA solutions for vehicle ECU maintenance, telemetry data stores, and NoSQL databases were discussed, followed by the critical role of rule engines and API gateways in IoT infrastructure. The vehicle telematics gateway was detailed, noting its software components. Finally, the development process was compared between cloud applications and embedded software.
In the next chapter, we will deep dive into the deployment and maintenance of an automotive IoT application and understand...
