The use of a cloud service requires a company to trust the vendor to comply with given Service-level Agreements (SLA). This work proposes a framework for modelling and maintaining Quality of Service levels expressed as SLA's through the definition of families of clouds as software service line organisations. By systematically exploiting the commonalities within related cloud systems while managing variations for specific customers, we relate variability to SLA's facilitating their monitoring, controlling and enforcement. Coupling the abstraction capabilities of product line approaches and SLA's to ensure Quality of Service in Cloud Computing is a novel approach, which offers the possibility to support dynamic negotiation of QoS parameters.

In the long run, our work aims to provide a generic framework for non-functional requirements enforcement in the Cloud.
