A framework for automated SLAs management in service-oriented environments

摘要

To meet their business goals, organizations are increasingly demanding services that can meet their functional and quality-of-service (QoS) requirements. In this paper, we propose a framework for service provisioning, which relies on brokered Service Level agreements (SLAs) between service consumers and service providers. The framework aims at providing support for automated SLA negotiation and management. The Service Broker of the framework carries out SLA negotiation, on behalf of service consumers, with selected service providers in multi-rounds of negotiations until an agreement or a timeout is reached. In each round, multiple SLA parameters are negotiated and both parties try to maximize their global utility functions. SLA compliance monitoring relies on the monitoring infrastructure, which provides support for independent monitoring of services by third party measurement services.
