Distributed fog and edge applications communicate over unreliable networks and are subject to high communication delays. This makes using existing distributed coordination technologies from cloud applications infeasible, as they are built on the assumption of a highly reliable, low-latency datacenter network to achieve strict consistency with low overheads. To help implement configuration and state management for fog platforms and applications, we propose a novel decentralized approach that lets systems specify coordination strategies and membership for different sets of coordination data.
