The major shortcoming of Grid middleware systems is the lack of economic-enhanced Grid services. These new services are necessary in order to let Grid users benefit from the properties of the Grid. Those properties comprise the availability of on-demand computational power, simplicity of access to resources, low cost of ownership, and a pay-for-use pricing(More)
Currently, the Internet service provider market offers two different types of pricing plans. In the USA, the predominant pricing plan is a flat-rate plan. In Europe and Asia, the predominant one is a per-minute pricing plan. Enrolled in such a pricing plan, users have to pay for the connect time to the Internet. Although Internet Service Providers (ISPs)(More)
This paper discusses the rationales for a Grid market and, in particular , the introduction of a market place for trading commoditized computing resources. The market place proposed makes computing resources from different providers substitutable through virtualization. This includes the definition of a spot and future market as well as the parameters that(More)
pricing of network services, charging for network services, QoS pricing, DiffServ, performance modeling This paper describes a control mechanism for Internet traffic. It is an economic mechanism that enables users to choose different price/QoS priority levels for network services at the user time scale. User time scale means that prices vary at a rate(More)
In the business Grid environment, the business relationship between a customer and a service provider should be clearly defined. The responsibility of each partner can be stated in the so-called Service Level Agreement (SLA). In the context of SLA-based workflows, the business model is an important factor to determine its job-resource-mapping policy.(More)
Service Level Agreements (SLAs) are currently one of the major research topics in Grid Computing. Among many system components for supporting SLA-aware Grid-based workflow, the SLA mapping mechanism receives a prominent position. It is responsible for assigning sub-jobs of the workflow to Grid resources in a way that meets the user's deadline and minimizes(More)
— The current Internet Service Provider market does not offer different types of service plans for Internet access. The predominant pricing plan is a flat-rated plan. Since the number of new Internet users is still growing very fast, there is no real competition in the Internet market. Consequently, there is no incentive for Internet Service Providers(More)
