Interactive real-time applications, either for soft or hard real-time, require strong QoS guarantees which, nowadays are only achievable through distinct hardware and software. The ICT FP7 project IRMOS (http://www.irmosproject.eu) will unite two distinct worlds - Service Oriented Infrastructures (SOIs) and real-time applications - in order to cope with soft real-time requirements. For that purpose, IRMOS is developing an SLA management framework, as part of the IRMOS virtualised service platform, considering all involved parties through the whole value chain. This includes the mapping of high-level application parameters to low-level resource provision attributes of the virtual environment, having a key role in all steps of the application lifecycle (requirements definition, SLA negotiation, monitoring application execution and SLA violation detection). The IRMOS SLA management framework is being validated, among others, by an application scenario which provides a distributed work environment for virtual and augmented reality, namely COVISE - COllaborative VIsualization and Simulation Environment.
