The vehicle is a cloud node. We build the bridge.

Connected Car Platform Engineering

Every modern vehicle is a connected device — and the cloud backend powering it determines the quality of every digital service, from remote diagnostics to over-the-air updates. We architect and build the backends that make connected vehicle features reliable, scalable, and compliant.

TL;DR

We design and build connected car backend platforms: MQTT/AMQP brokers, OTA update infrastructure, vehicle data pipelines, and digital service APIs. Our platforms handle millions of vehicle connections, comply with UNECE WP.29 cybersecurity regulations, and integrate with existing OEM backend systems.

The connected car ecosystem is one of the most demanding environments in cloud engineering. Millions of vehicles connected simultaneously. Sub-second latency requirements for remote commands. Zero tolerance for OTA update failures. UNECE WP.29 cybersecurity obligations. GDPR constraints on vehicle and driver data. Building this right requires deep expertise in both cloud-native architecture and automotive domain knowledge.

Vehicle Connectivity & Messaging Infrastructure

The foundation of any connected car platform is the messaging layer. We design and operate MQTT/AMQP broker infrastructure capable of handling millions of persistent vehicle connections — using AWS IoT Core, Azure IoT Hub, Eclipse Mosquitto, or HiveMQ depending on your requirements. We implement authentication using X.509 certificates, message authorization policies, and connection state management at scale.

OTA Update Backend Architecture

Over-the-air software updates are the highest-risk operation in the connected car stack. Our OTA backend architecture includes: cryptographic package signing (UNECE WP.29 R156-compliant), staged rollout control with health monitoring, automatic rollback triggers on failure metrics, and full audit logging of every update campaign. We integrate with existing vehicle software stacks and support delta update strategies to minimize bandwidth usage.

Vehicle Digital Services Platform

Remote lock/unlock, climate pre-conditioning, vehicle status APIs, and companion app backends — digital services require low-latency command routing, reliable state synchronization, and GDPR-compliant data handling. We build these service layers using event-driven architectures (AWS EventBridge, Azure Event Grid, Apache Kafka) that decouple vehicle-side and cloud-side concerns and scale elastically with fleet size.

Compliance: UNECE WP.29 & GDPR

UNECE WP.29 Regulation 155 (cybersecurity management) and Regulation 156 (software updates) are now mandatory type approval requirements across major markets. We design platform architectures that satisfy both regulations: CSMS documentation, penetration testing integration in CI/CD pipelines, and software update audit trails. GDPR vehicle data handling is implemented at the ingestion layer with consent management and data subject request workflows.

Frequently Asked Questions

What is UNECE WP.29 and how does it affect our connected car platform?
UNECE WP.29 is the United Nations Working Party for vehicle regulations. Regulation 155 mandates a Cybersecurity Management System (CSMS) for vehicle type approval, and Regulation 156 mandates a Software Update Management System (SUMS). Both are now required for new vehicle type approvals in the EU, Japan, South Korea, and other signatory markets. Your connected car platform's OTA infrastructure and cybersecurity architecture directly determine whether you can meet these requirements.
How do you scale MQTT infrastructure to millions of vehicles?
We use managed MQTT services (AWS IoT Core, Azure IoT Hub) for most projects — these scale automatically without cluster management overhead. For projects requiring on-premise or sovereign cloud deployment, we operate HiveMQ or EMQX clusters with horizontal scaling and load balancing. Connection state is externalized to Redis or DynamoDB for broker statelessness.
Can you integrate with our existing vehicle software stack (e.g., AUTOSAR, GENIVI)?
Yes. We design backend APIs and connectivity protocols that are agnostic to the in-vehicle stack. Our cloud APIs can be consumed by AUTOSAR-based telematics control units, Android Automotive OS applications, or custom RTOS-based connectivity modules. We provide reference client SDKs and integration documentation for in-vehicle software teams.
What happens if an OTA update fails mid-deployment on a vehicle?
Our OTA architecture implements multiple failure safety mechanisms: atomic partition switching (A/B update), automatic rollback on boot failure, health beacon monitoring post-update, and campaign-level rollback triggers if a failure rate threshold is exceeded. Update state is persisted in the cloud backend, so interrupted updates can be resumed. We design these mechanisms to satisfy WP.29 R156 requirements.
