The Open Reference Case A Reference Use Case for the SLA@SOI Framework

Abstract

The Open Reference Case (ORC) is a Software as a Service (SaaS) solution supporting the sales process in supermarkets. Within the European research project SLA@SOI, the ORC is used as an open source demonstrator to highlight features offered by the SLA management framework. As per the vision of SLA@SOI, the ORC runs on a virtualised infrastructure operated by an infrastructure provider. The ORC also allows for the inclusion of services offered by external service providers, such as banks. Such external providers are used in this scenario to highlight the process of negotiating SLAs between the ORC and an external provider. More generally, the interactions defined in the ORC scenario cover the SLA negotiation phase as well as the automated provisioning of software and monitoring of SLA violations.
