Abstract
Service Level Agreements (SLA) describe the rights and obligations of parties involved (typically the service consumer and the service provider); amongst other information they could include the definition of compensations: penalties and/or rewards depending on the level of service provided. We coin the concept of Compensable SLAs to such that include compensation information inside. In such a context, in spite of important steps towards the automation of the management of SLAs have been given, the expression of compensations remains as an important challenge to be addressed. In this paper we aim to provide a characterization model to create Compensable SLAs; specifically, the main contributions include: (i) the conceptualization of the Compensation Function to express consistently penalties and rewards. (ii) a model for Compensable SLAs as a set of guarantees that associate Service Level Objectives with Compensation Functions. We provide some properties and aspects that have been used to analyse two real-world SLAs.
