A geographical-aware state deployment service for Fog Computing

Today's distributed mobile applications assume a permanent network connectivity to mediate the interactions between a large number of users, coordinated by resourceful servers on cloud datacenters. Cloud-based distributed applications penalize performance with the unavoidable latency and jitter resulting from the geographical distance between clients and application servers. Fog Computing architectures mitigate this impact by deploying state fragments and providing computing power on surrogate servers, located at the network edge. Performance improves with the ability to deploy each fragment at the most convenient surrogate, and with efficient consistency procedures even when fragments at different locations are used. This paper presents a self-configuring geographical-aware state deployment service that combines a state deployment algorithm with a scalable distribution support framework.
