Advanced QoS Methods for Grid Workflows Based on Meta-Negotiations and SLA-Mappings

Overview

In novel market-oriented resource sharing models, resource consumers pay for the resource usage and expect that non-functional requirements for the application execution, termed as Quality of Service (QoS), are satisfied. QoS is negotiated between two parties following the specific negotiation protocols and is recorded using Service Level Agreements (SLAs). However, most of the existing work assumes that the communication partners know about the SLA negotiation protocols and about the SLA templates before entering the negotiation. However, this is a contradictory assumption, if one considers computational Grids and novel, commercially oriented computing Clouds where consumers and providers meet each other dynamically.
