Case Study: a European automotive software company reduces modernization costs and simplifies platform architecture with vFunction

Europe’s Most Respected Automotive Brands Software Company halves platform maintenance costs with vFunction

The software company behind Europe's most respected automotive brands faced significant challenges modernizing its large, complex Java-based platform for connected vehicles. The platform, a distributed monolith with 11 million lines of code, had accumulated technical debt that constrained engineering velocity. The company turned to vFunction to understand its architectural complexity and safely refactor the system for cloud-native platforms like Amazon EKS without disrupting service to millions of vehicles.

vFunction provided analysis that revealed dozens of tightly interwoven domains, which helped the team create a simplified, business-aligned target architecture of nine domains. Using vFunction's interactive architectural studio and structured modernization plan, the company shifted to an AI-assisted refactoring approach. This new strategy provided clear architectural visibility and is projected to reduce the platform's annual maintenance and operating budget by half.
