Removing the need for state dissemination in grid resource brokering

Abstract

Resource brokering in Grids is nowadays handled by resource brokers that require detailed knowledge of the state of the resources that they broker. In business settings, surrendering internal information on resources to an outside party is not an option. The traditional resource brokering method based on intimate resource knowledge is therefore not a viable possibility.This paper argues that the publication of resource state data is not needed for resource brokering. Instead, we advocate the use of service level agreements (SLAs). The use of SLAs for brokering lets providers keep state information internal and at the same time provides customers with guarantees on the used services.The proposed model has been implemented in the form of a resource broker that is based on Web Service technology. It shows that the approach of using SLAs for scheduling is a possible solution to keeping resource state private.

Client Requirement Modeling Using Resource Broker Architecture in Cloud Computing Environment

“…The use of SLA for brokering of services provided by various vendors [5] was discussed. By the use of SLAs broker gives opportunity to vendors to keep their resource information internal and secure and at the same time provide the users guarantee on required service submitted.…”

A Hierarchical Approach to Service Negotiation

“…The idea of treating resources as services was also proposed in [11]. However, our approach is different in that the same style of interaction -negotiation -is used for working with other service providers and with local resources.…”

“…However, our approach is different in that the same style of interaction -negotiation -is used for working with other service providers and with local resources. In contrast, in [11], the resource "wrapper" is treated as a "resource broker". Sierra et al [12] present a model of service negotiation closely based on classical models of two-party, multi-issue negotiation.…”

QoS-Based Decision Services in Grids

“…The agreement service is therefore not only resource-specific; it is also provider-specific. Furthermore, our model replaces the necessity of publishing resource state information (contrary to existing resource brokers) by guarantee terms in SLAs [18]. The broker's SLA negotiation is triggered by the service consumer.…”
