Service Level Agreements provide the foundation to negotia te for a distinct Quality of Service level between the provider and the consumer of a service. Since the Grid com munity is adopting concepts of Service-Oriented Architectures and Web Services are capturing their space wi thin the Grid landscape, resource management within Grids increasingly evolves towards the management of resou rces represented as services. To make allowance for this the Global Grid Forum develops the Web Services Agre ement specification to support standardised creation and negotiation of guarantees related to services. Th is paper illustrates the integration of a Web Services Agreement-based resource management framework into the UN ICORE Grid system, a development motivated by the system’s transition towards a service-oriented Grid an d the limitations of the current solution.
