Project Overview
The project for Erwin Hymer Group involved developing a comprehensive IoT platform that manages onboard systems in thousands of motorhomes, processes real-time vehicle telemetry through Kafka, and provides APIs for mobile and web applications supporting fleet management, rentals, and customer service.
The Challenge
Unify a connected fleet across Europe.
EHG needed a unified IoT platform to connect and monitor thousands of motorhomes across Europe while streamlining their business operations across multiple brands and countries. They faced challenges with fragmented systems for fleet management, rental operations, and customer service. The platform needed to handle real-time telemetry data from vehicle onboard systems, process millions of IoT events daily, and provide reliable APIs for mobile and web applications.
Kafka processing millions of vehicle IoT events daily for fleet monitoring and diagnostics.
The Solution
One IoT platform for the whole fleet.
Built a Java and Kotlin microservices platform with Kafka processing millions of IoT events from connected motorhomes daily. Azure IoT Hub connects to onboard vehicle systems providing real-time diagnostics, location tracking, and maintenance alerts. The microservices expose RESTful APIs powering rental management, fleet tracking, and customer service applications. Deployed on Azure with Kubernetes for automated scaling and high availability across European regions.
Technology Stack
Java and Kotlin microservices with Kafka event streaming and Azure IoT Hub for onboard connectivity, deployed on Kubernetes across European regions.
Azure
Azure provided the cloud foundation for EHG's IoT platform. The solution integrates Azure IoT Hub for device connectivity, App Services for APIs, and managed databases to create a scalable infrastructure capable of handling thousands of connected vehicles and processing millions of telemetry events daily across European operations.
