AQUAMan: An Adaptive QoE-Aware Negotiation Mechanism for SaaS Elasticity Management
نویسندگان
چکیده
Client churn is a key challenge confronted by SaaS providers. Recent research in QoE suggested providers should rely on quantiles & percentiles to assess the service acceptability rate. In this article we introduce AQUAMan, an Adaptive QoE-Aware multi-agent negotiation mechanism for SaaS elasticity Management. Based on its estimation of the percentage of users finding the service acceptable and a learned model of the user negotiation strategy, AQUAMan adjusts the provider negotiation process in order to restore the desired service acceptability rate while meeting the budget limits (i.e. the cost paid to rent cloud resources) of the provider. The proposed mechanism is implemented and its results are examined and analyzed in light of comparable results.
