Service oriented applications define the Quality of Services (QoSs) in terms of a Service Level Agreement (SLA) which guaranties the non-functional attributes for the users. However, web services usually have unpredictable load conditions and fluctuating demands which make it difficult to maintain the predefined SLA.
