Architecture of the CARUSO Ecosystem: Bringing a Marketplace for Car-Related Data and Services Up to Speed

May 2018 Presentation
Matthias Naab (Fraunhofer IESE), Jens Knodel (Fraunhofer IESE)

This presentation reports on the architects' work in creating the ecosystem for CARUSO, a B2B marketplace brokering data and services around car telematics.


Software Engineering Institute



CARUSO is a neutral B2B data and service marketplace around telematics services for drivers, vehicles, and fleets of vehicles. Thus, CARUSO establishes an ecosystem of parts suppliers, workshops, trade organizations, insurances, fleet and leasing organizations, and other companies in the automotive aftermarket. Building up the ecosystem is a key cornerstone of the digital transformation of a traditional industry. This comes with many unknowns and requires a high degree of flexibility.

This talk shares architecture experiences from establishing the ecosystem in the constant tension of business, legal, and technology. The way to a successful ecosystem leads through many experiments and requires constant revision of decisions. Key challenges are the openness of the ecosystem with high security and trust at the same time. Further, growing an ecosystem first requires a set of high quality offerings in the marketplace; there is a continuous need to align the onboarded partners' offering and consuming data and services. The ecosystem needs to be attractive for new partners, in particular in the early phase of startup.

The objective of this talk is to share experiences about ecosystem architecture that go far beyond technical architecture aspects.
