Global Automaker's Event-Sourced Supply Chain Control Tower

The Introduction

A global automotive manufacturer needed to modernize the mainframe monolith behind its Vehicle Monitor and Control System (VMACS). The goal: end-to-end visibility across its outbound supply chain, covering every vehicle, every carrier and every route segment, from factory completion to dealership arrival.

The team agreed the next version would be built on proven design principles: Domain-Driven Design, CQRS, and event sourcing. Rather than build and maintain an in-house framework, it chose a purpose-built, open-source foundation for event-driven architecture.

“The approach and relationship our company invested in with Axoniq on Control Tower will be easily reused in more areas of our company around the world.”

The Challenge: Tracking Every Vehicle, Factory to Dealer

The manufacturer needed a global track-and-trace application that could follow every vehicle from factory to dealership. Accurate arrival estimates were critical: multiple lines of business depend on them to release payments at the right time.

Design Criteria: The Bar the Manufacturer Set

• Flexible and scalable

• Enterprise security

• High availability

• Fully auditable

• Cloud ready

The Solution: An Event-Sourced Supply Chain Control Tower

The manufacturer’s new Control Tower application tracks each vehicle’s route plan from factory completion to dealership arrival. Arrival times, mode of transport, route-segment bottlenecks, and delay reasons are recorded as an immutable sequence of events, across every carrier and handoff. Because every movement is captured as it happens, the position and history of any vehicle can be reconstructed at any point in time, including across the handoffs where visibility used to break. The audit trail is the system of record, not a log bolted on beside it.

The application runs in a five-node cluster across two separate bare-metal data centers, meeting the business’s availability and security bar. As the manufacturer extends the pattern to other parts of its supply chain, the foundation is designed to move into its own Virtual Private Cloud on Google Cloud Platform.

Business Impact

The manufacturer now has provable, end-to-end visibility across its outbound chain, with straightforward scaling as volumes grow. ETAs the business can trust mean payments release on time across every line of business that depends on them, and the same track-and-trace pattern extends to the rest of the supply chain.
