Today's computing is largely delivered as services whereby computation, software, information, and IT infrastructure are provided without requiring end-user knowledge of the physical location and configuration of the service-delivering systems. Since there is a proliferation of services offered by different providers, quality of service is used to differentiate functionally equivalent services. This talk will start with a quick look into service quality landscape: definition, characteristics, activities, and management of quality of service. Then a number of quality attributes considered at service discovery/design time, including fault tolerance, security, privacy, provider trustworthiness, granularity, and agility, will be addressed.
Particularly, an approach to provision and measurement of these quality attributes will be presented.
