Monitoring of Service Level Objectives (SLOs) determines an essential part of Service Level Agreement (SLA) management, since customers are to be reimbursed, if a provider fails to fulfil them. By automating this process, a timely detection of a violation is possible. The compliance approach must be flexible to adapt to potential changes, must be scalable with respect to the amount of data, and has to support multidomain environments. This paper determines a Hosted Streaming Services scenario and defines relevant SLOs. Key requirements are derived, the respective architecture is designed, and the approach is implemented prototypically based on a generic auditing framework. Further-more, a new scheme is proposed that considers the degree and duration of SLO violations in calculating reimbursements.
