Summary

System design is a complex and challenging task, but it is essential for creating systems that are reliable, scalable, and meet the needs of the users. In this chapter, we introduced the system design process of an automotive IoT application and explained the UXDD approach. We then dived into the remote diagnostics use case and understood the current and new UX that product planning teams want to deliver, then we identified the high-level system components required to realize the remote diagnostics use case. We then did a further deep dive into vehicle telematics gateways and cloud platforms. We explored various vehicle telematics gateway technologies and the design trade-offs and decomposed the cloud platform to understand the foundational modules/subsystems required to realize remote application use cases. Once we had established the building blocks, we explained the classic vehicle diagnostics approach and upcoming SOVD. Finally, we looked at other key aspects such as regulatory...
