Global Connectivity Architecture for Automotive Data Plans

The Challenge

The central challenge was building a modular, scalable architecture that works across different markets, vehicle releases, and regulatory requirements. The system needed to enable seamless communication between vehicle, backend services, customer app, web portal, and multiple international mobile network operators – while accounting for their specific API standards, data formats, and business processes.

Our Solution

We developed a modular end-to-end architecture that connects all involved systems – vehicle, backend services, app, web portal, and mobile network operators. The focus was on flexible, adapter-capable interfaces that cleanly abstract different MNO protocols, various markets, and future extensions. Our architecture maps the entire user journey: from vehicle selection through data plan purchase and activation to renewal. Technically, the solution is based on a scalable AWS microservice stack with Prometheus/Grafana for monitoring and alerting, plus Apache Kafka for event-driven communication.

The Result

The result is a global connectivity platform that reliably and scalably supports millions of vehicles across different markets. The architecture enables a seamless user experience – from initial purchase to data plan renewal – while remaining open for integration of new mobile operators, vehicle models, and market requirements. Through comprehensive monitoring, precise documentation, and close collaboration with project teams, we created a maintainable, extensible solution that meets Porsche's high quality standards.
