Long-term Cloud Service Selection using Short-term Trials

Dr. Sheik Mohammad Mostakim Fattah


Abstract: There are two primary subscription models for IaaS cloud services: a) pay-as-you and b) reservation. Reservation-based subscriptions are typically offered for a long-term period such as 1 to 3 years. Long-term subscriptions are cost-efficient than short-term subscriptions for consumers who need services for a long-term period. Large organizations such as airline companies, banks, and research institutes tend to utilize IaaS services on a long-term basis for economic reasons. The performance of IaaS services is a key criterion to consider when selecting a service for a long-term. Selecting a service that may exhibit poor performance in the future may cause a significant loss of revenue for a business organization. Most IaaS providers however are reluctant to provide detailed information about their long-term service performance. We present a novel long-term cloud service selection framework where IaaS providers reveal limited performance information about their services. The proposed framework leverages free short-term trials to help consumer in making an informed decision.
