"We propose a novel approach to select IaaS cloud services for a long-term\nperiod where the service providers offer limited QoS information. The proposed\napproach leverages free short-term trials to obtain the previously undisclosed\nQoS information. A new significance-based trial scheme is proposed using\nfrequency distribution analysis to test a consumer's long-term workloads in a\nshort trial. We introduce a novel IaaS signature technique to uniquely identify\nthe variability of a provider's QoS performance. A Signature-based QoS\nPerformance Discovery (SPD) algorithm is proposed which leverages the\ncombination of free trials and IaaS signatures. A set of exhaustive experiments\nwith real-world datasets is conducted to evaluate the proposed approach."
