45 million vehicles, 90 markets, 12+ iconic brands, each with its own data silos, standards, and infrastructures.

In this episode, Chetan Alatagi, Solution Architect reveals how they transitioned from fragmented legacy ETL silos to a Unified Data Ecosystem—a global data streaming highway that turns vehicle telemetry into real-time value.

Chetan joins Joseph to go under the hood of a multi-region, multi-cloud architecture powered by Apache Kafka® and Confluent Cloud that ingests petabytes of vehicle telemetry, enforces data governance from edge to cloud, and powers mission-critical use cases like real-time emergency services, friction data alerts, and automated compliance across the entire Volkswagen Group.

You'll Learn:

How CARIAD ingests, governs, and distributes vehicle data at petabyte scale across a multi-cloud, multi-region architecture
Why Apache Flink® was the best option for stateful processing and how CARIAD balances Confluent Cloud for Apache Flink with self-managed clusters to achieve global flexibility and meet regional regulatory requirements
How CARIAD migrated multiple brands onto a unified event highway with near-zero data loss through Schema Registry and backward compatibility

Whether you’re battling Apache Kafka operational overhead or building a global data mesh, this episode is a blueprint for large-scale platform modernization and real-time fleet analytics.
