The composition of services has been a useful approach to integrating business applications within and across organizational boundaries. In this approach, individual services are federated into composite services which are able to execute a given task subject to a Service Level Agreement (SLA). An SLA is a contract agreed between a customer and a service provider who define a set of several Quality of Services (QoS). An SLA violation penalty is a way to ensure the credibility of an advertised SLA by a service provider. This paper considers a set of computer resources used by a service broker who represents service providers to host enterprise applications for differentiated customer services subject to an SLA and its violation penalty.
