A supporting infrastructure for evaluating QoS-specific activities in SOA-based Grids

Abstract

Despite the advances that have been made in Grid acceptance and adoption, further efforts are needed to ensure that the required level of service predictability is achieved. QoS issues require close attention, especially those aspects related to the evaluation of specific service activities with the aim of ensuring that the execution of a task produces an outcome according with its expectative behaviour. In this paper we present a supporting infrastructure to enable organisations to tackle the lack of tools for evaluating QoS-specific service activities. Additionally, we describe a case study that illustrates the applicability of the proposed model to general-purpose service management issues. The model has been tested in a controlled environment with promising results.
