Modelling and measuring the quality of online services




Quality of services, quality of service model, service-oriented computing, services.


A distributed application may be composed of global services provided by differentorganisations and have different properties. Providing provisioned services is of primaryimportance due to the multi-tenant and potentially multi-provider nature of servicecomputing paradigms. Quality of Services (QoS) has been used as a distinguishingfactor between similar services and as a criterion for service selection. To date, themajority of research on QoS is not comprehensive in identifying QoS suitable for onlineopen environments with diverse services.In addition, a lot of studies that is dedicatedto build QoS models are omitting the evaluation methods for many QoS. Therefore,there is a need for a QoS model that is comprehensive. Accordingly, the contributionin this paper compromises a generic QoS model that identifies a comprehensive QoSmetrics and their evaluation approaches. As a consequence, this study should be auseful reference to academic and industry researchers in the web-based service andonline service discovery, selection, composition, and management. Experiments areconducted to test various QoS metrics from the proposed QoS model.
