| Abstract | The upcoming business model of providing software as a service (SaaS) bears a lot of challenges to a service provider. On the one hand, service providers have to guarantee a certain quality of service (QoS) and ensure that they adhere to these guarantees at runtime. On the other hand, they have to minimize the total cost of ownership (TCO) of their IT landscape in order to offer competitive prices. The performance of a system is a critical attribute that affects QoS as well as TCO. However, the evaluation of performance characteristics is a complex task. Many existing solutions do not provide the accuracy required for offering dependable guarantees. One major reason for this is that the dependencies between the usage profile (provided by the service consumers) and the performance of the actual system is barely described sufficiently. Software Performance Curves are performance models that are derived by goal-oriented systematic measurements of the actual software service. In this paper, we describe how Software Performance Curves can be derived by a service provider that hosts a multi-tenant system. Moreover, we illustrate how Software Performance Curves can be used to derive feasible performance guarantees, develop pricing functions, and minimize hardware resources. |
