Semantic SLA for Clouds: Combining SLAC and OWL-Q

Abstract

Several SLA languages have been proposed, some specifically for the cloud domain. However, after extensively analysing the domain’s requirements considering the SLA lifecycle, we conclude that none of them covers the necessary aspects for application in diverse real-world scenarios. In this paper, we propose SSLAC, where we combine the capabilities of two prominent service specification and SLA languages: OWL-Q and SLAC. These languages have different scopes but complementary features. SLAC is domain specific with validation and verification capabilities. OWL-Q is a higher level language based on ontologies and well defined semantics. Their combination advances the state of the art in many perspectives. It enables the SLA’s semantic verification and inference and, at the same time, its constraint-based modelling and enforcement. It also provides a complete formal approach for defining non-functional terms and an enforcement framework covering real-world scenarios. The advantages of SSLAC, in terms of expressiveness and features, are then shown in a use case modelled by it.
