Cloud computing with single server threshold and double congestion thresholds

Cloud computing with single server threshold and double congestion thresholds

In this work, we study how to minimize the average system delay in a cloud computing center with heterogeneous servers, where each server may have a different average service rate. We consider M ∕ M i ∕ C ∕ K with a single server threshold and double congestion thresholds. The analytical models and...
