  The amount of software in modern cars is increasing continuously with
traditional electric/electronic (E/E) architectures reaching their limit when
deploying complex applications, e.g., regarding bandwidth or computational
power. To mitigate this situation, more powerful computing platforms are being
employed and applications are developed as distributed applications, e.g.,
involving microservices. Microservices received widespread adoption and changed
the way modern applications are developed. However, they also introduce
additional complexity regarding inter-service communication. This has led to
the emergence of service meshes, a promising approach to cope with this
complexity. In this paper, we present an architecture applying the service mesh
approach to automotive E/E platforms comprising multiple interlinked
High-Performance Computers (HPCs). We validate the feasibility of our approach
through a prototypical implementation.
