Abstract:
Economic, reliability, and low latency benefits of the cloud computing model are the result of a high level of dynamic resource sharing, made possible by a high degree of system interconnectivity. This paper suggests a more nuanced view of the effect of interconnectivity and resource sharing since interconnectivity may contribute to system fragility, which is associated with a possibility of abrupt/discontinuous system transition to a persistent overloaded regime with unacceptably high delays. This possibility is a result of the same system interconnectivity, which enables not only desirable but also undesirable load transfer throughout the networked system. Our results indicate that benefits of dynamic queuing disciplines, including low latency, can be realized provided that the relevant systemic risks of undesirable contagion are eliminated or mitigated. Due to the intractability of conventional performance models of large-scale interconnected systems, we use the “Complex Systems” methodology, e.g., a mean-field approximate performance model.
