Overview
AWS re:Invent 2025 – Accelerating the Connected Future: EDA for the unpredictable (IND308)
In this session, Christian Mueller (AWS) and Ludwig Goohsen (BMW Group) explain how BMW modernized the backend for its Connected Drive remote services using a serverless, event‑driven architecture on AWS.
Key points covered
- Migration from a monolithic Java EE application on Amazon EKS to a solution built with API Gateway, Step Functions, Lambda, SNS, SQS, and DynamoDB.
- Two‑week pilot for the Remote Horn Blow and Remote Light Flash use cases, achieving sub‑second P99 latency while processing > 1 million requests.
- Business outcomes: 60 % faster time‑to‑market, 20 % cost reduction, near‑zero infrastructure maintenance, and blue‑green deployment capabilities.
- Technical decisions such as GraalVM native compilation for Lambda cold‑start reduction, subscription filters for efficient event routing, and a serverless vehicle simulator for testing.
- Current scale: 2.5 million daily events and 100 million API calls, supporting 24.5 million connected vehicles with capacity to triple by 2027.

Introduction: BMW and AWS Partnership on Remote Services Modernization
Welcome to day one of AWS re:Invent 2025. In the next hour we’ll explore how BMW accelerates the connected future by adopting an event‑driven architecture for its unpredictable workloads using AWS serverless services.
When we first engaged in 2023, BMW already had a functional remote‑services solution that met business requirements. However, both teams wanted to transform a good solution into a great one by applying the highest standards.
Presenters
- Christian Mueller – Principal Solutions Architect, AWS (partnered with BMW for five years).
- Ludwig Goohsen – Product Manager, Remote Services Backend, BMW Group.
Agenda
- Overview of BMW Connected Drive and its remote‑services offering.
- Architecture in place in 2023 (monolithic Java EE on EKS).
- New serverless architecture, design decisions, and lessons learned.
- Iterations and refinements made after the initial rollout.
- Business benefits realized after production deployment.
BMW Connected Drive: Scale and Impact of Remote Services
BMW Group’s connected‑services portfolio spans BMW, Mini, and Rolls‑Royce under the Connected Drive brand. Features include:
- MyBMW smartphone app
- In‑car gaming and streaming
- Large‑language‑model‑based personal assistant
These services turn a vehicle from a simple transport device into an intelligent, connected companion.
Fleet Size & Data Volume
- Connected vehicles: > 24.5 million (largest fleet globally)
- Over‑the‑air updates: > 10.5 million per release cycle
- Daily traffic: > 16.6 billion requests, > 184 TB of data processed
The platform must handle rapid growth; traffic and request volumes are expected to triple within two years.
MyBMW App
- Active users: 50 million
- Rating: 4.8 stars (iOS & Android)
The app delivers live vehicle data, service recommendations, dealership appointment booking, and remote‑service controls—core topics of this breakout session.
