Current fog systems rely on centralized and strongly consistent services for
configuration management originally designed for cloud systems. In the
geo-distributed fog, such systems can exhibit high communication latency or
become unavailable in case of network partition. In this paper, we examine the
drawbacks of strong consistency for fog configuration management and propose an
alternative based on CRDTs. We prototypically implement our approach for the
FReD fog data management platform. Early results show reductions of server
response times of up to 50%
