Grid Comput., Vol. 2, Num. 4, pages 323-339, 2004.
   Abstract: We have developed and implemented the Relational Grid Monitoring Architecture (R-GMA) as part of the DataGrid project, to provide a flexible information and monitoring service for use by other middleware components and applications. R-GMA presents users with a virtual database and mediates queries posed at this database: users pose queries against a global schema and R-GMA takes responsibility for locating relevant sources and returning an answer. R-GMAs architecture and mechanisms are general and can be used wherever there is a need for publishing and querying information in a distributed environment. We discuss the requirements, design and implementation of R-GMA as deployed on the DataGrid testbed. We also describe some of the ways in which R-GMA is being used.

1. Jonatha Anselmi, Danilo Ardagna, Paolo Cremonesi. A QoS-based selection approach of autonomic grid services. SOCP '07: Proceedings of the 2007 workshop on Service-oriented computing performance: aspects, issues, and approaches, pages 1-8, ACM, 2007.
   Abstract: The Web service composition (WSC) is the process of building an instance of an abstract workflow by combining appropriate Web services that satisfies given QoS requirements. In general, QoS requirements consists of a number of constraints. The selection process requires global optimization and can be formalized as a mixed integer linear programming problem which cannot be solved in polynomial time. However, since the number of submitted workflows is large and the QoS is highly dynamic, the fast selection of composite Web Services is particularly important. In this paper, we present a QoS broker-based framework for Web services execution in autonomic grid environments. The main goal of the framework is to support the broker in selecting Web services based on the required QoS. To achieve this goal, we propose a novel approach: since successive composed Web services requests can have the same task to Web service assignment, we address the Multiple Instance WSC (MI-WSC) problem optimizing simultaneously the set of requests which will be submitted to the system in the successive time interval instead of independently computing a solution for each incoming request. Experimental results show that the proposed algorithm has better performance with respect to existing techniques. Moreover, the qualities of the selected composite Web services are not significantly different from the optimal ones.

   Abstract: QoS-Based Services Selecting and Optimizing Composition between the peers play an increasingly important role to ensure interoperability on Grid environment. However, the prohibitive cost of selecting, matching, mapping and composing algorithm has now become a key bottleneck hindering the deployment of a wide variety of Grid services. In this paper, we present QoS-Based Services Selecting and Optimizing Composition on Grid. First, it checks requesters' semantic in order to form candidate service graph. Second, it designs service selecting and mapping algorithms for optimizing the model. Third, it creates an executed plan of optimum composition on Grid. We conducted experiments to simulate and evaluate our approach.

   Abstract: The deployment of grid services should make the services, including those to be deployed and those already deployed, operate with desired functionalities and qualities. The critical challenge in the deployment is that many technical and nontechnical factors have to be taken into account, such as performance, reliability, utilization, operating cost, incomes, and so on. Since the factors change continuously, some deployed services may have to be redeployed for guaranteeing their functionalities and qualities. This position paper presents an approach to the deployment and redeployment of grid services based on software architecture models. In this approach, all services in a grid consist in a software architecture, which represents the services, their relationships and other factors in a global, understandable and easy-to-use way. To demonstrate the approach, a visual tool for deploying services onto a set of popular grid infrastructures, including J2EE application servers and BPEL engines, with the help of software architectures is developed.

   Abstract: Successful realization of the Open Grid Services Architecture (OGSA) vision of a broadly applicable and adopted framework for distributed system integration, virtualization, and management requires the definition of a core set of interfaces, behaviors, resource models, and bindings. This document, produced by the OGSA working group within the Global Grid Forum (GGF), provides a first version of this OGSA definition. The document focuses on requirements and the scope of important capabilities required to support Grid systems and applications in both e-science and e-business. The capabilities described are Execution Management, Data, Resource Management, Security, Self-Management, and Information. The description of the capabilities is at a high-level and includes, to some extent, the interrelationships between the capabilities.
