Popis: SaaS cloud computing is gaining momentum in recent years with more and more successful application adoptions. Processes of these applications often comprise a series of services mapping to users' work flows and a consumer has to designate a particular provider for each service when deploying an application. As long as the provider fails to deliver the service, all application processes which include the service will discontinue their execution even though some other providers may offer the same service. In this paper, we propose a SaaS framework to support dynamic service composition based on QoS criteria of SLA. Each service is brokered and delivered to best fit the criteria specified when it is requested. Applications running on this framework will therefore obtain optimal performance.
