Engineering an SLA Checker Using MDA Technologies

Overview SLAng is a language for expressing Service Level Agreements (SLAs), specified using technologies of the Model Driven Architecture approach (MDA), including the Meta-Object Facility model (MOF) and Object Constraint Language (OCL). This paper describes the motivation and experience in applying additional MDA technologies, including the Java Meta-data Interface (JMI) mapping and an OCL evaluator, to the automated generation of a software component for detecting SLA violations in service performance data. The paper highlights correctness and ease of implementation as particular benefits of the approach. These are significant as SLAs may form part of legal contracts and are expressed in a language that is subject to a degree of change.
