    <title language="eng">Opening up New Fail-Safe Layers in Distributed Vehicle Computer Systems</title>
    <abstract language="eng">The automotive industry currently faces several challenges, including a growing complexity in system architecture. At the same time, the task load as well as the needs for performance increase. To address this problem, the A3Fa research project evaluates scalable distributed concepts for future vehicle system architectures. These can be seen as comparable to cluster-computing systems, which are applied in high-performance or high-availability use-cases. Methods used in such scenarios will also be important features in future vehicle architectures such as horizontal application scalability, application load balancing and reallocation, as well as functionality upgrades triggered by the user.&#13;
This paper focuses on concepts and methods for the reliability of applications and hardware in future in-vehicle distributed system architectures. It is argued that future automotive computing systems will evolve towards enterprise IT systems similar to today’s data centers. Furthermore, it is stated these vehicle systems can benefit greatly from IT systems.&#13;
In particular, the safety against failure of functions and hardware in such systems is discussed. For this purpose, various of such mechanisms used in information technology are investigated. A layer-based classification is proposed, representing the different fail-safe levels.</abstract>

    <title language="eng">Performance Isolation of Co-located Workload in a Container-based Architecture for Automobile</title>
    <abstract language="eng">As the development in the automotive sector is facing upcoming challenges, the demand for in-vehicle computing power capacity increases and the need for flexible hardware and software structures arises, allowing dynamic managament of resources. In this new scenario, software components are to be added, removed, updated and migrated between computing units. To isolate the software components from each other and allow its orchestration, a container-based virtualization approach is being tested throughout this research. The analysis focuses on the question if this virtualization technology could be an option to ensure an interference-free operation. Four different sample applications from the automotive environment are tested for their susceptibility to resource contention. The research on the one hand shows that CPU and memory used by an application can&#13;
be largely isolated with this technology, but on the other hand, it&#13;
becomes apparent that support for I/O-heavy usage is currently&#13;
not implemented sufficiently for container engines.</abstract>
