Multi-User Service Selection

Modern service selection in a cloud has to consider multiple requests to various service classes by multiple users. Taking into account quality-of-service requirements such as response time, throughput, and reliability, as well as the processing capacities of the service instances, we devise an efficient algorithm for minimum-cost mapping of mutually independent requests to the corresponding service instances. The solution is based on reduction to transportation problems for which we compare the optimal and a suboptimal but faster solution, investigating the tradeoff. In comparison to the alternative service selection models, the evaluation results confirm the efficiency and scalability of the proposed approach(es).
