Connected Vehicle Platform Architecture
Vendor-neutral architecture for suppliers, new entrants, mobility startups, and OEM teams designing, selecting, or rescuing a connected vehicle cloud platform — vehicle-to-cloud messaging, OTA, telematics, and the identity and regional deployment that make it hold up for a full product generation.
The proof: the connected vehicle platform our founder architected at a global automaker became its reference platform across four regions (NA, EU, AU, IN) — tens of millions of connected vehicles, still in production on current-generation models. One example of the depth: re-architecting vehicle messaging onto MQTT-over-mTLS cut remote command round-trip from 30+ seconds to under 5 seconds.
What a connected vehicle platform has to get right
Vehicle-to-cloud messaging — MQTT over mTLS with per-vehicle identity; command/response semantics that are idempotent and survive lost connectivity; store-and-forward for telemetry. Kafka, AWS IoT Core, or Google Pub/Sub as the backbone — chosen per region and workload, not per vendor pitch.
Multi-region, multi-brand deployment — Data residency, regional regulatory services (accident notification, SOS, stolen-vehicle location), brand-specific features on one codebase, active-active where uptime is regulated.
OTA and update security — Uptane-based OTA: multi-signature key management, TUF metadata, threshold signatures, offline/online key separation, key rotation, attack detection.
Identity at fleet scale — Vehicle identity (PKI, digital key) and customer identity (OAuth2/OIDC) on the same platform; zero-downtime migrations proven at 15M+ users.
Telematics and analytics — Ingestion for safety, conformity, and operational analytics; edge/cloud split; the unglamorous parts (idempotency, observability, audit trails) that decide whether the platform survives year three.
Remote services and digital key — Remote start, lock, and climate, diagnostics, service requests, cross-vehicle profile sync — designed to execute in seconds, globally.
Build, buy, or license?
Most teams asking "which OTA or telematics platform should we license" are really asking three questions: what must stay in-house (vehicle identity, the command path, the data), what a vendor can own without locking you in (fleet console, OTA campaign tooling, analytics), and what the exit costs when the vendor's roadmap diverges from yours. We run that assessment vendor-neutral — reference architecture, evaluation criteria, and a recommendation you can put in front of procurement — because we've built and operated the in-house version at OEM scale.
How we engage
Architecture review — An independent read of an existing or proposed platform: what will hold up, what won't, and what to change before it ships.
Platform selection and build-vs-buy — Evaluation criteria, vendor shortlist, reference architecture, and a defensible recommendation.
Fractional chief architect — Ongoing ownership of platform architecture for teams that don't have one in-house.
RFP/RFQ support — Technical response and architecture for connected-services bids.
Delivery — Advisory through full-team build.
Adjacent platform work
The same discipline carries to multi-tenant SaaS (tenant isolation, per-tenant configuration, event-sourced state), real-time messaging and event streaming, and IoT beyond vehicles (bike telemetry, connected health devices).
